Copart vs IAAI: Which Auto Auction Should Importers Choose?

Comparing America's two auction giants: where to find better inventory, lower buyer fees, and reliable damage reports.

Over 90% of US vehicle imports originate from Copart and IAAI (Insurance Auto Auctions). Both platforms auction insurance, bank-repossessed, and dealer trade-in inventory.

However, there are fundamental differences in inspection transparency, fee structures, and salvage title sourcing.

1. Inspection Rigor and Condition Transparency

IAAI is widely recognized for more thorough condition reports, including engine audio/video recordings and IAAI 360 View panoramas.

Copart features a much larger daily inventory (175,000+ lots), but includes more third-party flipper listings. Always run a Carfax report before bidding on Copart.
