Copart vs. IAAI: A Side-by-Side Breakdown
If you're looking to buy a vehicle through a salvage or insurance auto auction, two names dominate the landscape: Copart and Insurance Auto Auctions (IAAI). Both platforms offer thousands of vehicles every week at potentially significant discounts — but they operate differently, serve different audiences, and have distinct fee structures. This guide breaks down everything you need to know before registering.
Overview of Each Platform
Copart
Founded in 1982, Copart is one of the largest online vehicle auction platforms in the world, operating in over 200 locations across the United States and internationally. It sells vehicles on behalf of insurance companies, banks, charities, and fleet operators. Most inventory consists of collision, theft-recovery, repossession, and low-value vehicles.
IAAI (Insurance Auto Auctions)
IAAI was founded in 1982 as well and is now owned by KAR Global. It similarly sells on behalf of insurers and fleet owners, with hundreds of locations in the U.S. and international operations. IAAI has historically had a strong reputation among licensed dealers, though it has expanded access to the public in recent years.

Fees: What to Expect
Both platforms charge buyers beyond the hammer price. Understanding these fees is critical to calculating your true cost of acquisition.
- Buyer's fee: A percentage or flat fee added on top of the winning bid, tiered by sale price.
- Membership/registration fee: Copart requires an annual membership; IAAI charges a registration deposit.
- Gate/storage fees: If you don't pick up your vehicle promptly, daily storage fees accrue quickly.
- Virtual bid fee: Some online bidding incurs an additional charge per lot.
Always use each platform's official fee calculator before placing a bid — fees can add 15–30% or more to the final purchase price.
Which Platform Has Better Inventory?
Copart generally has a larger overall inventory, especially for newer model year vehicles and clean-titled cars. IAAI often has a strong supply of fleet vehicles and can be a great source for specific makes and models depending on your region. It's worth searching both platforms before committing to a bid.
Who Should Use Each Platform?
- Copart is ideal for first-time buyers, international exporters, and those who want the largest selection.
- IAAI works well for licensed dealers, experienced rebuilders, and buyers focused on condition-graded inventory.
Final Thoughts
There's no clear "winner" between Copart and IAAI — the best platform depends on what you're looking for. Many experienced buyers maintain accounts on both and shop wherever inventory meets their needs. Take time to register, explore listings, and understand the fee structures before you place your first bid.
