What it adds to every lot page
The full VIN
Where the auction hides the last digits, we show the complete VIN whenever we have it, ready to copy.
The real cost
Buyer fee, gate fee, online bidding fee and taxes, added up for any bid in the auction's currency.
The car's history
Earlier sales and relists of the same car, with the prices they reached.
Market prices
Recent sold comparables and a suggested max bid from the retail value and the repair estimate.
One-click actions
Save the lot, set a max bid, write a note or watch the VIN, synced with your account and the apps.
Badges in search results
Lots we know are marked right in the auction's own results pages.
