About CoBid
Your Copart UK auction companion.
CoBid helps you follow the cars you care about and see an estimated total alongside the current bid, including fees.
TRACK YOUR LOTS
Paste a lot ID from your loaded Copart UK auction queue. See the vehicle name, current bid and queue position in your watch list.
HEAR WHEN YOUR CAR IS ON THE BLOCK
Get a sound alert when a watched lot moves onto the block, even with the extension popup closed. Use Test sound before the auction and keep your device volume on.
SEE BIDS WITH ESTIMATED FEES
View the current bid alongside an estimated total. Adjust your fee profile, bidding channel, VAT and additional charges in Settings.
KEEP YOUR WATCH LIST
Follow multiple lots and retain auction-ended records with the last observed bid. Your watch list and settings are stored locally in Chrome, with no developer-operated analytics or cloud account.
GET STARTED
1. Open and load a Copart UK auction lane.
2. Open CoBid and add a lot ID from that lane's queue.
3. Check your fee settings and press Test sound.
4. Keep the auction page open for tracking and alerts.
IMPORTANT
This early release supports copart.co.uk only. It does not place bids. Updates depend on Copart's displayed data, the loaded lane and your connection. Estimated totals are not invoices and may exclude transport, storage or other charges unless you account for them in Settings. Check your membership fees and the vehicle's VAT treatment. An ended auction does not necessarily mean the seller has accepted the bid.
CoBid is an independent tool and is not affiliated with, endorsed by or operated by Copart.
