How to Get a Pre-Purchase Inspection for an Auction Car

Bidding on an auction car you’ve never seen in person is one of the riskier things you can do in the collector-car hobby. A pre-purchase inspection (PPI) by an independent specialist is the single best way to reduce that risk.

What Is a Pre-Purchase Inspection?

A PPI is an independent evaluation of a vehicle by a qualified mechanic or specialist — someone who works for you, not the seller. A good PPI covers:

• Mechanical condition: Engine, transmission, brakes, suspension, steering
• Body and paint: Repaint evidence, accident history, rust or corrosion
• Documentation: Title, VIN, service records
• Specific to your marque: Compression/leak-down (air-cooled Porsches), frame condition (FJ40s), matching-numbers verification (classic muscle cars)

Step 1: Find an Inspector in the Right City

The car is where the seller is — not where you are. Search for an inspector who is local to the listing, not local to you.

Use AuctionInspectors to find specialists by marque and city. For rare marques or remote locations, a generalist mechanic with strong references is better than no inspection at all.

Step 2: Contact the Inspector Early

Auction windows are short — often 7 days on BaT, 10 days on PCarmarket. Contact your inspector on day 1 or 2. Most specialists need 24–48 hours to schedule with the seller and complete their report.

Step 3: The Inspector Contacts the Seller

On enthusiast platforms (BaT, Cars & Bids), sellers are almost always cooperative. They want serious bidders. Your inspector will reach out directly using the contact information in the listing.

On salvage platforms (Copart, IAA), inspectors with yard access will schedule a visit during business hours.

Step 4: Review the Report

A good inspection report includes:

• Compression and leak-down numbers (for engines where this applies)
• Photos of problem areas
• An honest assessment of whether the asking price (or expected hammer price) reflects the car’s condition

Step 5: Bid or Walk Away

Armed with real data, you can bid with confidence — or pass without regret. The inspection fee is cheap insurance against a six-figure mistake.
