Copart vs IAAI vs Manheim: Which Car Auction Is Best?

Copart and IAAI (Insurance Auto Auctions) both specialise primarily in insurance salvage and total-loss vehicles, while Manheim focuses on dealer, fleet and lease-return stock that is typically in cleaner, roadworthy condition. If you want the widest choice of damaged and rebuildable vehicles, Copart and IAAI dominate; if you want low-mileage clean-title cars at wholesale prices, Manheim is usually the stronger source, though its buyer network is more dealer-orientated. See our Copart buying guide for the full registration process.

Copart has the largest inventory by volume, with over 200 locations and the biggest selection of salvage and rebuildable vehicles. IAAI, owned by the same parent company as Manheim's rival KAR Global historically, tends to have slightly stronger relationships with certain insurers in the Midwest and can offer better deals on late-model salvage vehicles. Manheim's stock skews toward clean and reconstructed titles from dealer trade-ins and off-lease vehicles, making it the best choice if you specifically want to avoid heavily damaged cars.

Copart's buyer fees run roughly 8-12% of hammer price including virtual bidding charges. IAAI's fee structure is broadly similar, often slightly lower on mid-range lots but with a comparable internet bidding fee (IB fee). Manheim charges a buyer fee typically calculated as a percentage with a cap, and dealer-only auctions may require a licensed dealer or broker to bid on your behalf, which is where using a shipping and buying agent like The Ship Cars becomes valuable for private overseas buyers.

Copart offers the most straightforward international registration process, with a well-established internal export documentation service. IAAI similarly welcomes overseas members but has a smaller international support team. Manheim is more restrictive — many of its auctions are dealer-only, meaning private overseas buyers usually need to work through a licensed buying agent to access lots, adding a small commission but opening up higher-quality stock.

For salvage, rebuildable and project cars destined for a full IVA-tested UK registration, Copart's scale and photo/video documentation make it the easiest starting point. If you specifically want late-model, low-mileage vehicles with clean titles and don't mind working through a broker, Manheim often delivers better value per pound spent. IAAI sits in between and is worth checking in parallel with Copart for the same make and model, since prices for similar lots can vary meaningfully between platforms in the same week.
