Copart vs. IAAI: Which Auction Platform Is Better?

Copart and IAAI (Insurance Auto Auctions Inc.) are the two dominant auto auction platforms in the USA. Here's how they compare.

Inventory Size

Copart: ~200,000+ active lots at any time. Larger selection, especially for newer vehicles.

IAAI: ~150,000+ active lots. Strong in commercial vehicles and fleet cars.

Fees

Both use tiered buyer premium structures. Copart's fees are slightly higher on average, but they also tend to have more competitive starting prices.

Technology

Copart: Better mobile app, more detailed vehicle photos (10-15 per lot), VR walkaround for some vehicles.

IAAI: Solid platform but fewer tech features. Good search filters.

Vehicle Condition

Both platforms receive vehicles from the same insurance companies. The condition mix is similar. Copart has a slight edge in the number of clean title vehicles.

International Buyers

Copart: More international-buyer-friendly. Better export documentation process.

IAAI: Requires a US-based broker for most international purchases.

Our Verdict

Bid2Doors currently works with Copart due to their larger inventory and better international buyer support. We plan to add IAAI integration in the future.
