The bidding limit restricts the number of vehicles that you can be winning on at any given time. Some auctions will have bidding limits for new or unverified buyers.
When reaching your limit, you can continue to bid on any of your active vehicles. The restriction will also be automatically lifted if you are outbid, allowing you to bid on new vehicles.
If you are a bulk buyer and would like to have this limit removed, please contact firstname.lastname@example.org
