What Is Bonhams? The Auctioneer's European Heritage

Bonhams is one of the world's oldest auction houses, founded in 1793 and headquartered in London. While the company operates across multiple categories — fine art, wine, jewelry, collectibles — its automobiles division represents one of the most prestigious venues for selling and acquiring classic cars, exotic vehicles, and collectible sports cars.

What distinguishes Bonhams from competitors like RM Sotheby's and Gooding & Company is its European heritage and deep expertise in European automotive history. If you're buying a pre-war Bugatti, a British Jaguar, or a continental Ferrari, Bonhams' specialists bring a curatorial knowledge that goes beyond price guides. The auction house doesn't just sell cars — it tells stories about them.

The company holds major motor auctions throughout the year at prestigious venues including the Goodwood Festival of Speed, Scottsdale Arizona, Paris, Amelia Island, and Quail Lodge. Each event attracts collectors from around the world and typically offers 50–150 vehicles spanning multiple categories from affordable classics to rare, museum-quality examples.

Why Choose Bonhams? What Sets This Auction House Apart

Not all auction houses are equal. Bonhams has cultivated specific advantages for buyers who understand them:

European Car Expertise

Bonhams has unparalleled depth in European automotive history. The auction house's catalog specialists are deeply knowledgeable about pre-war marques, British classics, and continental sports cars. If you're buying a rare Ferrari Daytona or a Series 1 E-Type, the condition assessments and provenance documentation reflect specialist-level expertise.

Competitive Buyer's Premium

Bonhams' buyer's premium typically ranges from 12% to 15%, plus applicable taxes. This is competitive with RM Sotheby's (typically 15%) and lower than some international venues. The transparent fee structure means you know exactly what you're paying.

Curated Catalogs

Unlike online auction platforms that accept anything submitted, Bonhams curates its catalogs. The company actively rejects vehicles that don't meet its standards or don't fit the event's market focus. This means every car in the catalog has been vetted, photographed professionally, and assessed by specialists. Fewer surprises. Higher quality across the board.

Comprehensive Provenance Documentation

Bonhams publishes detailed lot descriptions including ownership history, service records, restoration details, and known issues. The auction house also provides condition reports for high-value vehicles. You get transparency that elevates the auction experience above casual online bidding.

Global Audience

Bonhams' major events attract serious collectors from Europe, Asia, and North America. This international bidding pool drives fair market pricing and ensures competitive results for well-presented vehicles.

Major Bonhams Motoring Events in 2026

Bonhams holds several signature automotive auctions throughout the year. Understanding the event calendar helps you plan your bidding strategy:

Goodwood Festival of Speed (Summer)

Held annually during the Goodwood Festival of Speed in Sussex, England, this event attracts some of the finest cars in European private collections. Expect significant pre-war cars, British classics, and rarities rarely seen at auction. Very competitive bidding.

Scottsdale, Arizona (January)

Bonhams' Scottsdale event typically draws 80–120 vehicles and attracts North American collectors and international bidders. The market skews toward American classics, muscle cars, and accessible collector vehicles alongside European marques. Generally more competitive pricing than Goodwood, with broader variety.

Paris (February)

The Paris event focuses heavily on European collector cars and attracts significant European bidding participation. Strong results for French marques, Italian sports cars, and continental classics.

Amelia Island, Florida (March)

Coinciding with the Amelia Island Concours d'Elegance, this auction attracts serious collectors seeking museum-quality and significant vehicles. Strong results for pre-war and early post-war cars, with premium pricing for exceptional examples.

Quail Lodge, California (May)

Held during the prestigious Quail Lodge Invitational, this event draws West Coast collectors and bidders seeking high-quality American and international classics. Intimate setting with strong price realization.

Step 1: Registration — Getting Approved to Bid

Before you can bid at Bonhams, you must register. The process is straightforward but requires documentation and pre-approval:

Online Registration

Visit bonhams.com and navigate to the specific auction event. Create an account and complete the bidder registration form. You'll provide contact information, bidding history (if applicable), and banking details for settlement after purchase.

Phone Registration

Call Bonhams' motor sales team directly to register by telephone. This option is useful if you have questions about the process or want to discuss your bidding intentions with a specialist. International buyers often prefer this method for clarity.

In-Person Registration

If you're attending the auction in person, you can register on-site during the event. Bring a government-issued ID and be prepared to provide banking information. Most buyers register during preview day or the morning of the auction.

Required Documentation

Bonhams will ask for:

  • Valid government-issued ID (passport for international buyers)
  • Proof of funds or financing pre-approval letter
  • Bank details for settlement (wire transfer, typically)
  • Address and contact information
  • Any existing Bonhams bidding history or references

Deposit Requirements

First-time bidders or buyers seeking to bid on high-value lots ($500,000+) may be required to place a refundable deposit, typically 10–20% of your estimated bidding activity. For a buyer planning to bid up to $500,000, expect a deposit in the $50,000–$100,000 range. This deposit is held in escrow and credited against your purchase if you win.

Returning bidders with established history typically bypass deposit requirements on smaller lots. Once registered, your status remains active across multiple Bonhams events during the calendar year.

Step 2: Catalog Research — Understanding Lot Descriptions and Estimates

The Bonhams catalog is your primary research tool. Published 3–4 weeks before the auction, the catalog is available online and in print. Understanding how to read it dramatically improves your buying decisions.

Lot Numbers and Descriptions

Each vehicle is assigned a lot number (typically 1–150, depending on event size). The description includes year, make, model, body style, engine type, and mileage. Bonhams provides ownership history spanning years or decades, restoration details, and known service records.

Condition Reports

For high-value lots (typically $200,000+), Bonhams publishes detailed condition reports covering bodywork, mechanical condition, upholstery, and known issues. The report uses clear language about restoration status, repairs needed, and current running condition. Read these carefully — they're written by specialists.

Estimate Ranges

Each lot includes a low and high estimate, typically reflecting market value based on comparable sales, condition, provenance, and rarity. Estimates are conservative relative to actual selling prices at major auction houses. Expect 20–40% of lots to exceed their high estimate, especially well-known vehicles and significant rarities.

Understand that estimates are not guarantees. A car estimated at $150,000–$180,000 might sell for $120,000 in a slow market or $220,000+ if two serious collectors compete for it. Use estimates as a data point, not a prediction.

Provenance Notes

Provenance — the documented history of ownership and use — dramatically impacts value. A Ferrari that's been in one family for 30 years commands premium pricing. A car with murky ownership history or "missing years" will be discounted. Read provenance carefully. If it seems vague or incomplete, ask questions during preview days.

Step 3: Viewing and Preview Days — Inspecting Before You Bid

Bonhams provides viewing days before each auction event. This is where due diligence happens. Plan to spend time with the cars you're considering.

What to Expect

Preview days typically begin 2–3 days before the auction and run through the afternoon before bidding starts. Vehicles are displayed in climate-controlled facilities or outdoor preview areas. You can examine any vehicle in the catalog, open doors, sit in seats, and ask questions of Bonhams' specialists on-site.

What to Look For

If you're a collector, you likely know what to assess in a car of interest. If you're less experienced, focus on these key areas:

  • Panel gaps and paint consistency: Uneven panel gaps suggest poor restoration or accident repair. Use a paint depth gauge if you're serious about a high-value vehicle.
  • Interior condition: Originality is valued in classic cars. Assess upholstery, dash condition, odometer reading (is it consistent with mileage claimed?), and any modifications.
  • Engine bay: Look for signs of quality restoration, original parts, cleanliness, and any obvious mechanical issues or repairs. Don't shy away from asking the on-site specialist questions.
  • Running condition: Ask if the car was recently started or run. Some vehicles at auction haven't been driven in months. A car that runs and starts tells you more than one sitting idle.
  • Documentation: Ask to see service records, title documents, and any restoration reports. Comprehensive documentation increases confidence and value.

Bringing a Specialist

If you're serious about a high-value purchase, hire an independent pre-purchase inspection specialist before preview day ends. Many auction attendees bring their own mechanics or marque specialists to assess condition and identify deferred maintenance. A $2,000 specialist inspection can save you $50,000 in hidden repair costs.

Automonitor offers pre-auction inspection services specifically designed for major auctions. We can coordinate with Bonhams' staff to arrange detailed inspections during preview periods.

Step 4: Bidding Options — How to Place Your Bid

Bonhams provides multiple bidding methods to accommodate different buyer preferences:

In-Room Bidding

Attend the auction in person and bid from the gallery. You'll be assigned a paddle with your bidder number. Raise it to bid, and the auctioneer will acknowledge your bids. This is the most engaging experience but requires travel and time commitment. In-room bidders often receive acknowledgment and interaction with the auctioneer and can gauge market sentiment in real time.

Telephone Bidding

Register to bid by telephone. A Bonhams representative calls you during the auction and relays bids on your behalf. This works well if you're unavailable to attend in person but want real-time bidding control. You must be available at a specified time and maintain clear phone communication throughout bidding. International buyers frequently use this method.

Online Bidding (Bonhams App and Website)

Bonhams' online bidding platform allows you to place bids in real time from anywhere with internet access. The interface shows the live auction, current bid price, and allows you to place incremental bids. Mobile app bidding offers full functionality on tablets and smartphones. This is the most accessible method for remote bidders, though it requires concentration and reliable internet.

Absentee/Commission Bids

If you can't attend or bid in real time, submit an absentee bid specifying the maximum price you're willing to pay for a lot. Bonhams will execute the bid on your behalf, bidding as minimally as possible up to your limit. If multiple absentee bids exist, the highest one wins at the second-highest bid increment. Commission bids are filled on a first-come, first-served basis if they're equal.

Absentee bidding is convenient but carries a disadvantage: the auctioneer knows there's a ceiling price, which can artificially suppress bidding below your maximum. Use absentee bids for lesser-desired lots where you want to participate passively, not for highly sought vehicles.

Understanding Buyer's Premium and Fees

The hammer price is not your final cost. Bonhams charges a buyer's premium on top of the hammer price, plus applicable taxes:

Buyer's Premium Structure

Bonhams' standard buyer's premium is 12% on most sales. Some high-value sales may be negotiated at 15%. This is added to your hammer price to calculate your total purchase obligation.

Example: A car hammers at $100,000. Your buyer's premium is $12,000 (12%). Your total is $112,000 before sales tax.

Sales Tax and VAT

Sales tax is due on most purchases in the United States (varies by state). If buying from the UK or Europe, Value Added Tax (VAT) may apply or be waived depending on your location and buyer status. International buyers may qualify for VAT exemptions if exporting vehicles outside the EU/UK. Clarify tax obligations before bidding.

Additional Charges

Some lot descriptions include notes about added charges (buyer's fees for specific lots, conservation fees for particularly sensitive vehicles, etc.). Read the fine print. Typically, hammer price + buyer's premium + taxes = your total cost. But always confirm.

How Bonhams Compares to RM Sotheby's and Gooding

Understanding how Bonhams stacks up against other major auction houses helps you choose the right venue for your purchase:

Factor Bonhams RM Sotheby's Gooding & Company
Buyer's Premium 12–15% 15% 12–15%
Specialty European Cars, British Classics All Categories, Global Collector Cars, American Focus
Events per Year 5–7 major 12+ 4–5 major
Average Hammer Price $200K–$400K $300K–$500K $250K–$450K
European Expertise Exceptional Very Good Good
Catalog Curation Highly Selective Selective Selective
Online Platform Quality Good Excellent Good
International Bidding Access Very Good Excellent Very Good

RM Sotheby's has more frequent events and a larger global footprint. Gooding & Company typically attracts higher average prices. Bonhams excels for European cars and offers competitive fees with exceptional specialist expertise in certain categories. Choose based on what you're buying and where you want to buy it.

Step 5: Post-Sale Process — Payment and Collection

Winning at auction is the beginning, not the end. Understanding post-sale logistics prevents costly delays:

Payment Timeline

Payment is typically due within 5 business days of the sale. Bonhams accepts wire transfers (preferred), certified checks, and some credit arrangements for qualified buyers. Late payments incur interest charges and potentially forfeiture of the vehicle.

Payment Methods

  • Wire Transfer: Fastest and preferred. Bonhams provides wire instructions. Confirm bank details with the auction house directly — never wire based on email instructions alone.
  • Certified Check: Accepted but slower to clear. Mail promptly to avoid payment deadline issues.
  • Financing: Many buyers arrange exotic car loans before the auction. Ensure your lender approves the specific vehicle and price before bidding.
  • Broker Purchases: If you're buying on behalf of a client or entity, ensure clear documentation and authorization before settlement.

Collection and Logistics

After payment clears, you must arrange collection of your vehicle. Options include:

  • Direct Collection: Arrange your own transport to the auction site and drive or trailer the car away. You must have valid title and insurance arranged before collection.
  • Bonhams Logistics: Some events offer logistics coordination for a fee. Bonhams can arrange transport from the auction venue to a destination address.
  • Third-Party Shippers: Hire independent car transport companies. Many Bonhams attendees use specialist shippers for high-value vehicles. Budget $2,000–$5,000 for domestic transport, more for international shipping.

Documentation and Title

Bonhams provides detailed post-sale documentation including the bill of sale, title transfer information, and any warranty documentation. For imported vehicles, ensure all documentation is in order before arranging transport, particularly if crossing international borders.

International Buying Considerations

Many Bonhams auctions attract international bidders. If you're buying from outside the sale venue's country, additional considerations apply:

UK/European Sales (Import to US)

Buying a car in the UK or Europe for import to the US requires:

  • EPA compliance verification (not all vehicles qualify)
  • Duty payment (typically 2.5% of value)
  • International transport ($5,000–$15,000 depending on origin)
  • Customs clearance and documentation
  • US title application and state registration

Many European cars cannot be imported to the US due to emissions and safety standards. Verify EPA eligibility before bidding. The process adds 4–8 weeks and significant costs but is straightforward if you understand the requirements.

US Sales (Export from US)

International buyers purchasing at US-based Bonhams events face simpler logistics — many vehicles are domestic market cars (no EPA barriers), and US exports are routine. Budget for international shipping and destination country import duties (highly variable by country).

Currency and Exchange Rates

If bidding in a foreign currency, factor exchange rate risk. Lock in rates with your bank if possible. Currency fluctuations can shift your total cost 5–10%. Wire transfers should be executed the same day you lock in rates to minimize exposure.

Common Mistakes Auction Buyers Make

Avoid these preventable errors:

Bidding on Emotion, Not Data

The auction environment is emotionally charged. Competitive bidding triggers adrenaline. Buyers frequently pay 20–30% above their pre-set limit because of "auction fever." Set a maximum bid before the auction and stick to it. If you exceed your limit, you've overpaid. Period.

Skipping the Condition Report

Don't bid on sight-unseen vehicles without reading condition reports. Similarly, don't attend preview day without reading the catalog first. You waste time assessing cars you should eliminate.

Not Accounting for Buyer's Premium

Inexperienced bidders calculate their max bid as the hammer price but forget to add 12–15% buyer's premium plus taxes. A $100,000 max bid becomes $112,000–$115,000+ with fees. Know your true bottom-line cost before bidding.

Assuming "As-Is" Means Perfect

Auction cars are sold as-is without warranties. Condition reports note known issues, but undisclosed problems can emerge after purchase. Get a pre-purchase inspection from a third party you trust. This is non-negotiable for purchases above $150,000.

Neglecting Insurance Arrangements

You need insurance before collection. Many buyers assume they can arrange it after winning. Insurance companies may decline to cover imported vehicles or vehicles with unknown provenance or cosmetic issues. Arrange coverage before bidding, or confirm your broker can place it immediately post-sale.

Missing Payment Deadlines

Five business days means five business days. Missing this deadline forfeits the vehicle and any deposit. Mark your calendar. Set a reminder. Wire funds early.

Financing Exotic Cars from Auction

Most exotic car purchases require financing. Key points for auction purchases:

Get Pre-Approved Before Bidding

Contact exotic car lenders like JJ Best Banc or Woodside Credit before the auction. Obtain pre-approval for your estimated purchase amount. This clarifies your actual buying power.

Lender Approval of Specific Vehicles

Lenders typically require approval of the specific vehicle before release of funds. Provide the lot number, condition report, and estimated hammer price. Allow 2–3 business days for lender approval after winning.

Interest Rates and Terms

Expect 6–10% interest rates for exotic cars, 20–30% down payments, and 36–84 month terms depending on the vehicle, your credit, and lender policies. Older or unusual vehicles may face higher rates or require larger down payments.

Gap Insurance

Consider gap insurance, which covers the difference between insurance payout and loan balance if the car is totaled. For exotic cars that depreciate, gap insurance provides peace of mind.

Insurance Considerations for Auction Purchases

Exotic cars require specialized insurance. Standard auto policies often exclude collector cars or limit coverage:

Agreed-Value vs. Actual Cash Value

Collector car policies typically use "agreed value" (both parties agree to a set value at policy inception) rather than "actual cash value" (insurance company's estimate at claim time). Agreed-value policies are crucial for exotic cars, which have highly variable market values.

Mileage Restrictions

Many collector car policies limit annual mileage to 2,500–5,000 miles. If you plan to drive your purchase regularly, ensure your policy reflects actual anticipated usage.

Storage and Usage

Insurers may require proof of secure storage (garage, not driveway) and may exclude certain uses (racing, towing, commercial use). Clarify these restrictions before purchase.

What to Do After Winning: Next Steps

After you've won and payment clears, several steps follow:

Title Transfer and Registration

Depending on the sale location and your state/country, complete title transfer documentation. This typically takes 2–4 weeks. Budget for registration and title fees (varies widely by location).

Inspection and Maintenance

Even if you obtained a pre-auction inspection, schedule a full post-purchase inspection with your preferred specialist or mechanic. Budget for deferred maintenance. Some cars run beautifully for 100 miles then need $20,000 in repairs. Identify issues early.

Valuation and Insurance Documentation

Document your purchase through photos, the bill of sale, and post-purchase condition reports. This protects your insurance claim if damage occurs. Have your vehicle professionally appraised for insurance documentation within 30 days of purchase.

Service Records and History

Maintain complete service records. Document every maintenance, repair, and improvement. This investment in record-keeping pays enormous dividends when you eventually sell. Read more about building provenance for future sales.

Should You Buy at Auction? When Auction May NOT Be Right

Auction purchases aren't always optimal. Consider alternatives:

Private Sales

Buying from a private collector avoids buyer's premium, offers negotiation flexibility, and often provides deeper ownership history. However, you lose the auction house's vetting and may encounter deception. Use caution with private sales and always get inspections.

Dealer Purchases

Established exotic car dealers often provide warranties, pre-purchase inspections, and recourse if problems emerge. Prices are typically higher (dealers mark up 15–25%), but the reduced risk may justify the premium for first-time exotic car buyers.

Concierge Buying Services

Automonitor's concierge buying service handles auction bidding, negotiation, inspection, and logistics on your behalf. This eliminates the learning curve and auction-day stress while ensuring expert due diligence.

Frequently Asked Questions

Can I return a car purchased at auction?

No. Auction cars are sold as-is with no right of return. This is why pre-purchase inspections are critical.

What if the car doesn't start or run after purchase?

You own it as-is. No recourse with Bonhams. This reinforces the importance of third-party inspections before winning.

How long does the entire auction process take from registration to collection?

Roughly 2–3 weeks from first viewing to vehicle in your possession, assuming straightforward logistics and no complications.

Can I bid if I'm financing?

Yes, but you must have proof of funds or a pre-approval letter from your lender to satisfy deposit requirements.

What happens if I win but can't pay?

You forfeit your deposit, face collection action from Bonhams, and may be blacklisted from future sales.

Are auction prices truly fair market value?

Generally yes, particularly at major events like Bonhams where competitive international bidding occurs. However, unusual vehicles or market anomalies can result in prices above or below comparable sales.

How accurate are pre-sale estimates?

Bonhams' estimates are typically conservative. Expect 20–40% of lots to exceed the high estimate, especially well-known or emotionally appealing vehicles. Estimates are data points, not predictions.

Should I attend preview in person?

For purchases above $250,000, strongly yes. Remote inspection isn't adequate for expensive decisions. For smaller purchases, preview attendance is optional but recommended.

The Bottom Line: Is Bonhams Right for Your Next Purchase?

Bonhams has auctioned exceptional vehicles for over two centuries. If you're buying a European classic, British sports car, or pre-war automobile, Bonhams' expertise is unmatched. The transparent process, curated catalogs, and specialist knowledge reduce surprises and support fair market pricing.

However, successful auction purchases demand preparation: research the catalog thoroughly, attend preview days or arrange inspections, set realistic bidding limits, understand all costs including buyer's premium and taxes, and arrange logistics and insurance in advance.

Do this homework, and auction purchasing becomes a straightforward path to acquiring exceptional cars. Skip these steps, and auction purchases become an expensive education in regret.
