How to Buy a Car at RM Sotheby's
RM Sotheby's hosts the world's premier collector car auctions, moving over $1 billion annually. Whether you're buying your first classic or adding to an established collection, this guide walks you through every step — from registration to the hammer.
What is RM Sotheby's? The World's Largest Collector Car Auction House
RM Sotheby's was founded in 1986 and has grown to become the world's premier collector car auction house, selling over $1 billion in vehicles annually. The company operates a global network of sales, with major auctions in Monterey, Amelia Island, Paris, London, Abu Dhabi, and Toronto. RM Sotheby's specializes in classic, sports, and exotic automobiles — the kinds of cars that appreciate, generate conversation, and attract passionate collectors from around the globe.
The auction house attracts serious buyers because of its uncompromising approach to cataloguing, provenance research, and condition assessment. Every car that enters the auction block has been thoroughly documented. Condition reports are detailed and honest. The estimates are based on real market data, not speculation. This reputation for integrity is what separates RM Sotheby's from lesser auction houses and why the hammer prices often exceed estimates.
If you're shopping for a collector car, RM Sotheby's should be on your radar. The selection, the quality of the cars, and the strength of the bidding all reflect the caliber of this auction house.
Major RM Sotheby's Events Throughout the Year
RM Sotheby's operates a year-round auction calendar, with flagship events that attract collectors from every continent. Understanding when and where these auctions take place is crucial for planning your purchase strategy.
Monterey Auction (August)
The Monterey auction is the marquee event on the RM Sotheby's calendar — the largest sale by volume and the auction that generates the most press coverage. Held during Monterey Car Week, this event attracts the world's most significant collectors. Expect 200+ lots, many of them headline-grabbing vehicles. Competition is fierce, estimates are aggressive, and prices tend to peak in August. If you're shopping for investment-grade cars or headline-making vehicles, Monterey is where to look. Learn more about choosing the right classic car auction house for your needs.
Amelia Island Auction (March)
The Amelia Island sale in Florida is the second major event on the calendar. Held in March during Amelia Island Concours d'Elegance week, this auction typically features 150+ lots with slightly less stratospheric estimates than Monterey. This is an excellent entry point for first-time auction buyers — the quality is top-tier, but the competition is marginally less intense.
Paris Auction (February)
RM Sotheby's sells in Paris each February, offering European collectors convenient access while attracting international bidders. European marques — Mercedes-Benz, Ferrari, Porsche, Alfa Romeo — are particularly well-represented. If you're hunting for a specific European classic, Paris is worth monitoring.
London Auction (October)
The London autumn sale brings British classics to the block — Jaguar, Aston Martin, Bristol, Bentley — alongside continental marques. This auction caters to the UK collector base and is smaller in scale than Monterey or Amelia Island.
Abu Dhabi Auction (November)
The November Abu Dhabi sale has become increasingly significant, attracting Middle Eastern collectors with substantial buying power. Expect premium vehicles and premium prices. This auction is worth watching if you're monitoring market trends in the ultra-premium segment.
Toronto Auction (September)
The Toronto sale is Canada's premier collector car auction, featuring North American classics alongside imports. Typically 100-150 lots, with mid-range estimates compared to Monterey.
How to Register as a Bidder: Documentation and Requirements
Before you can bid at RM Sotheby's, you must complete the registration process. This is not complicated, but it does require advance planning and proper documentation.
What You'll Need
- Valid Photo ID: Passport or driver's license. RM Sotheby's requires government-issued identification.
- Proof of Address: A recent utility bill or bank statement confirming your residential address.
- Financial References: Bank or credit card references to establish bidding credentials. You may be asked to provide contact information for your bank or credit provider.
- Deposit: A security deposit to establish your bidding paddle number. Typically $25,000-$100,000 depending on your expected bidding level. This is held as collateral and returned (or credited toward a purchase) after the auction.
- For First-Time Bidders: You may be asked to provide additional financial documentation or references from previous auction houses where you've bid.
Register at least 2-3 weeks before the auction. RM Sotheby's staff will review your application and confirm your bidding approval. Late registrants may not be approved in time to bid.
Understanding the Catalogue: Lot Descriptions, Provenance, and Estimates
The RM Sotheby's catalogue is the bible for auction participants. Every detail in the description matters. You need to read it carefully.
Lot Number and Title
Each car is assigned a lot number. The title describes the vehicle: year, make, model, and any notable features. "1964 Jaguar E-Type Series 1 Roadster" is straightforward. "1960 Ferrari 250 GT SWB" tells you it's a short-wheelbase variant. Details in the title are intentional and significant.
Estimate Range
Every lot carries an estimate — a range representing the auction house's prediction of the hammer price. Estimates are conservative. They're based on recent comparable sales, condition, provenance, and market sentiment. Hammer prices often exceed high estimates, particularly for exceptional cars or during strong market periods. Low estimates signal a car that may need work or has less documented provenance. High estimates suggest exceptional pedigree or condition.
Lot Description
The description details the car's history, specifications, condition, and any known issues. This is where honesty matters. RM Sotheby's will disclose known defects, previous repairs, or questions about originality. A thorough description runs 300-500 words and covers engine type, transmission, special features, service history, and any concerns.
Provenance
Provenance — the documented ownership history — is critical for collectible cars. Who owned the car? When? Are there gaps in the history? Was it owned by a notable collector or celebrity? Provenance directly impacts value. A 1970 Porsche 911 with a documented single-family ownership from new is worth significantly more than an identical car with unknown ownership gaps.
Condition Report
Every lot includes a detailed condition report available for download in the catalogue PDF. The report describes the exterior, interior, engine, transmission, brakes, suspension, and electrical systems in clinical detail. A 10-point scale is typically used (10 being concours-level condition). You should read the condition report before deciding to inspect a car.
Pre-Auction Preparation: Preview Days and Inspection Strategies
Smart auction buyers don't show up on auction day and start bidding. They prepare extensively.
Schedule Your Auction Visit
RM Sotheby's typically opens the sale for preview 2-3 days before the auction. Block your calendar. Plan to spend 4-6 hours at the preview examining the cars you're seriously considering. Bring a notebook, a camera, and a checklist.
Request a Condition Report
Before attending the preview, download and review the condition reports for your target lots. Flag any concerns. The condition report will tell you whether the car has mechanical issues, needs detailing, or has been expertly restored. Use this information to prioritize which cars to inspect in person.
Request an Authoritative Pre-Purchase Inspection
For lots over $50,000, hire a professional pre-purchase inspector to examine the car during preview days. At a minimum, this inspection should cover:
- Full engine diagnostic scan
- Compression and wet/dry compression testing
- Transmission function and fluid condition
- Brake system integrity and fluid condition
- Suspension geometry and component condition
- Paint depth measurement to detect repainting
- Undercarriage documentation
- Service history verification
A professional inspection costs $500-$1,500 but can reveal hidden issues that save you tens of thousands. Learn what to look for during a pre-purchase inspection. At Automonitor, we connect buyers with certified exotic car inspectors who know exactly what questions to ask during an auction preview.
Bidding Strategy: Set Your Maximum and Stick to It
Auction fever is real. People bid against each other in ways they would never bid alone. The trick is recognizing this dynamic and protecting yourself against it.
Calculate Your Total Budget
Before you bid, know your maximum price. This should include the hammer price plus the buyer's premium (typically 12-15%), plus taxes, plus shipping if you're buying from across the country. If the estimate is $150,000 and you estimate a 15% buyer's premium, you're looking at roughly $172,500 in total cost — before taxes and logistics. Know this number before you raise your paddle.
Understand Bidding Increments
RM Sotheby's uses standard auction bidding increments. As prices rise, the increments increase:
- Under $1,000: $50 increments
- $1,000-$5,000: $100 increments
- $5,000-$25,000: $500 increments
- $25,000-$100,000: $1,000 increments
- $100,000+: $2,500-$5,000 increments
At higher price points, you can bid without jumping by the full increment. Be strategic about increments in the final stages of bidding.
In-Room vs. Phone vs. Online Bidding
You have three bidding options:
In-Room Bidding: You sit in the auction hall and raise your paddle. Most experienced collectors bid in-room because you can observe other bidders, gauge market sentiment, and make split-second decisions about when to drop out. In-room bidding gives you psychological control.
Phone Bidding: You call into the auction house before the lot comes up, and a representative bids on your behalf. Phone bidding removes emotion from the process but also removes visibility. You can't see if other bidders are dropping out or sense the energy in the room. Phone bidding works if you're disciplined and you've set a firm maximum.
Online Bidding: RM Sotheby's live auctions are streamed online with real-time bidding capability. Online bidding combines the emotional involvement of in-room with the convenience of remote participation. This is increasingly popular for international collectors who can't travel to the auction.
Don't Get Caught Up in Auction Fever
The most expensive mistakes happen in the final moments of bidding, when two collectors are locked in a battle of ego. You bid $120,000. Someone else bids $125,000. Your paddle goes up immediately at $130,000. They bid $135,000. You bid $140,000 — above your maximum. They drop out. You win at $140,000 for a car you budgeted at $125,000.
Here's the defense: step away when the bidding approaches your maximum. Let someone else win. There will be another auction next month with another car at a better price. Discipline beats emotion every time in auction buying.
Understanding the Buyer's Premium: Calculate Your True Total Cost
The hammer price is not the actual price you pay. RM Sotheby's adds a buyer's premium — a commission charged to the purchaser on top of the hammer price.
Premium Structure
RM Sotheby's charges:
- 12% on the first $50,000 of the hammer price
- 15% on the portion of hammer price between $50,000 and $1,000,000
- 10% on any amount above $1,000,000
For a $100,000 hammer price, the total cost is $100,000 (hammer) + $6,000 (12% on first $50,000) + $7,500 (15% on remaining $50,000) = $113,500.
Calculate Before Bidding
Always calculate your all-in cost before you bid. If the estimate is $100,000-$120,000, don't assume you'll pay $100,000. Assume you'll pay closer to $135,000-$140,000 after premium and taxes. That changes your bidding strategy.
What Happens After You Win: Payment Terms and Logistics
Winning a car is the beginning, not the end. Here's what follows.
Payment Terms
RM Sotheby's requires payment within 5-7 days of the sale. Payment can be made via wire transfer, credit card (subject to a 3% processing fee), or bank check. Your initial deposit is credited against the final payment. If you deposit $50,000 and win at a $100,000 hammer price with 15% premium ($115,000 total), you owe an additional $65,000.
Title and Documentation Transfer
After payment clears, RM Sotheby's begins the title transfer process. This varies by location. For U.S. sales, most states require a bill of sale and a title document signed by both the seller (auction house) and buyer. The auction house will provide all necessary documentation. For imported vehicles or sales across state lines, you may need to work with a specialized transport company to handle DMV filings.
Arranging Transport and Logistics
Unless you're driving the car home immediately after purchase, you'll need to arrange transport. RM Sotheby's typically holds vehicles for 14 days post-sale. After that, storage fees ($50-$100/day) apply. You have three main options:
Hire an Open Truck: Cheapest option ($1,500-$3,500), but the car is exposed to weather and road hazards. Open carriers are standard for everyday vehicles.
Enclosed Transport: Safer option ($2,500-$5,000) with climate control and protection from the elements. Recommended for classic and valuable cars.
Bespoke Logistics: For ultra-premium vehicles, specialized movers provide door-to-door service with climate control, security, and full-time driver attendance. Costs $5,000-$15,000+ depending on distance.
Book transport immediately after you win. Popular carriers fill up quickly, especially after major auctions. Learn about shipping exotic cars across the country.
Financing Auction Purchases: Specialty Lenders and Pre-Approval
Most people don't pay cash for auction purchases. Financing is available, but you need to plan ahead.
Get Pre-Approved Before Bidding
Contact specialty lenders before the auction and get pre-approved up to your maximum bidding price. This gives you confidence and speed. After you win, you can immediately confirm financing without scrambling to find a lender at the last minute.
Specialty Lenders for Collector Cars
Traditional banks won't finance classic cars. You need lenders who specialize in the segment:
- JJ Best Banc: Specializes in exotic and collector car financing with flexible LTV ratios. Typically 20% down, rates 6-10% depending on vehicle and credit profile. Processing time: 5-7 days.
- Woodside Credit Union: California-based credit union with collector car expertise. Competitive rates for vehicles in good condition with verifiable provenance.
- Augmento Finance: Focuses on exotic and performance cars with rapid approval and funding. Higher rates (8-12%) but faster processing (48-72 hours).
Documentation Required for Approval
Lenders will want the auction house condition report, hammer price documentation, and a professional inspection report. They'll also verify the vehicle's history through CARFAX or equivalent. Bring everything to your lender pre-auction so there are no surprises post-win.
Common First-Timer Mistakes: What to Avoid
Auction veterans have made these mistakes so you don't have to.
Mistake 1: Not Inspecting the Car Before Bidding
You cannot assess a car's true condition from a photograph or catalogue description. A car might photograph beautifully but have a seized transmission or corroded frame rails. Always spend time with the car in person during preview. Walk around it. Open the doors. Check the undercarriage. Start the engine. Listen to it run. If you can't attend the preview in person, hire a professional inspector to do it for you.
Mistake 2: Not Calculating the True Total Cost
Too many buyers focus on the hammer price and ignore the premium, taxes, and shipping. You see a $100,000 estimate and think you're buying a $100,000 car. In reality, you're buying a $145,000 car once you factor in all costs. Know your true budget before you bid.
Mistake 3: Letting Auction Fever Take Control
It's exhilarating to win an auction. It's terrible to win at a price you regret. Set your maximum bid before the auction and stick to it no matter what. If you find yourself bidding above your maximum, step away immediately. Your future self will thank you.
Mistake 4: Missing Payment Deadlines
The 5-7 day payment window is firm. Late payment can result in penalties, interest charges, and even default on the sale. If you're financing, ensure your lender can fund within this window. Plan your wire transfer or payment vehicle in advance.
Mistake 5: Skipping Title Verification
Before you bid, verify that the car has a clean title. The auction house will disclose whether a car has a salvage, branded, or reconstructed title. Don't assume. Read the catalogue listing carefully. A salvage title can mean 30-50% lower resale value even if the car has been beautifully restored.
RM Sotheby's vs. Other Major Auction Houses
RM Sotheby's is the largest, but it's not the only option. Here's how it compares:
| Auction House | Annual Volume | Buyer's Premium | Specialization | Best For |

| Barrett-Jackson | $500M | 10% | American classics, celebrity vehicles | Hot rods, muscle cars, TV auction lovers |
RM Sotheby's dominates in prestige and international reach. Bonhams excels with European classics. Gooding & Company specializes in American automotive history.

Schedule Your Inspection →Frequently Asked Questions
Can I bid remotely if I can't attend the auction in person?
Yes. RM Sotheby's offers phone and online bidding for all registered bidders. However, in-room bidding gives you psychological advantages — you can see other bidders drop out and gauge the energy in the room. If you choose remote bidding, be especially disciplined about your maximum.
What if I win but can't pay within the 5-7 day window?
Contact the auction house immediately. Late payment can result in penalties up to 1.5% per month, plus potential default on the sale. In extreme cases, the auction house may offer the lot to the underbidder. Don't let this happen. Arrange financing before you bid.
Is the buyer's premium negotiable?
Not typically. However, if you're a major collector or planning to purchase multiple vehicles, you may be able to negotiate a reduced premium or special terms. This is handled directly with the auction house management, not at the registration desk.
Can I return a car if I'm unhappy after purchase?
No. All sales at RM Sotheby's are final and as-is. This is why the pre-purchase inspection is non-negotiable for high-value purchases. You are responsible for determining the car's condition and authenticity before you bid.
How accurate are the estimates in the catalogue?
Very accurate. RM Sotheby's estimates are conservative and based on recent comparable sales. Hammer prices typically fall within the estimate range or slightly above. An estimate of $80,000-$120,000 is a reliable guide to where a car will sell. Estimates serve the auction house — if they're too low, sellers won't consign. If they're too high, the auction house looks bad. Smart estimates are accurate estimates.
What if a car doesn't sell (doesn't meet reserve)?
If a lot doesn't reach its reserve price, it's "bought in" or "passed." You cannot purchase a car that was passed. If you're interested in that vehicle, the auction house can typically connect you with the seller for a private sale negotiation post-auction.
How do I verify a vehicle's title before bidding?
The auction house will disclose the title status in the catalogue. Look for language like "clear title," "branded title," or "salvage title." Contact the auction house directly if you need clarification. Never bid on a car with a salvage or heavily branded title unless you understand the implications for future resale and insurance.
What's the best time of year to buy at RM Sotheby's?
Monterey in August is the most competitive (highest prices). Amelia Island in March and London in October offer strong selection with slightly less aggressive bidding. Abu Dhabi in November attracts ultra-premium vehicles at premium prices. For value, consider smaller regional auctions or sales with lower-tier vehicles (estimate under $30,000). Competition is lower, and deals are available.
Final Thoughts: Trust the Process

But buying smart requires discipline. Do your homework. Get an inspection. Calculate your true cost. Set your maximum bid. And stick to it.
