You never really forget a good car.
Enter the registration of your old car. We watch the marketplaces in the background and tell you the moment it comes back up for sale.
From just £29/year, half a tank of petrol.
Because it wasn't just a car.
The flush of freedom that comes with your first car. Memories of long summer road trips. The smell of old leather and petrol in the classic you saved every penny for. It's easy to regret selling a car that meant something special, but finding it again is impossible when plates change and listings disappear in hours.
We look up the full history of your car and automate the search so you don't have to. Even if the plates do change, when it resurfaces, you'll be the first to know.
Three steps. Zero effort.
Set it once, we handle everything else.
Enter the reg
Type in the registration of a car you used to own. We'll check it's still on the road in the next thirty seconds.
We start watching
Every day we scan AutoTrader, eBay, PistonHeads and BidSpotter auctions for it. We also watch the MOT history: a sudden test pass after years parked up usually means a sale is coming.
You get the alert
The moment it appears for sale or shows signs of life, you get an email. Listings are matched on the registration, so it's your car, not a lookalike. Then it's all up to you.
MOT just passed!
Your 1987 Golf GTI passed its MOT yesterday after 3 years off the road. This car may be coming back.
We found your Dad's Porsche 911.
Listed for sale on PistonHeads. Matched on the registration. Good luck!
Your first car is back on the road.
R249 VBJ is now taxed and MOT'd. SORN lifted after 5 years. Keep watching for a listing.
This is what your garage looks like the moment we find your car.

Most people set up a saved search and hope for the best. We go further.
Marketplace scans
Daily checks across AutoTrader, eBay, PistonHeads and BidSpotter auctions. We match on the registration, from the advert or the plate in the photos, so you only hear about your car.
Private plate protection
Cars sometimes change identities. We watch previous registrations so the alert fires even if the plate is different.
MOT & tax monitoring
An MOT pass after years off the road is the most reliable sign a car is being prepped for sale. You'll know before it's listed.
Keeper changes
We watch how long the current keeper has had the car. After three or four years, the chance of a sale rises sharply. We adjust the watching accordingly.
The cost of half a tank of fuel.
Keep the memory alive for less than £3 a month.

Questions people ask
How can I find out if my old car is for sale?
Add its registration to Previous Keeper. Every day we scan AutoTrader, eBay, PistonHeads and BidSpotter auctions for your car, and email you when it's listed for sale. Plans with marketplace scanning start at £29 a year.
Can I track a car I used to own in the UK?
Yes, that's exactly what Previous Keeper is for. Enter the registration of any UK car you've owned, even if you sold it years ago, and we watch the marketplaces for it alongside its MOT, tax and SORN status from DVLA records. The current owner is never told.
How much does Previous Keeper cost?
Single is £29 a year for one car, Garage is £49 a year for up to 3 cars, and Collector is £99 a year for up to 10. There's also a free plan for one car, which covers MOT, tax and SORN alerts but doesn't include marketplace scanning. Less than half a tank of fuel to keep the memory alive.
Which marketplaces does Previous Keeper search?
Every day we scan AutoTrader, eBay, PistonHeads and BidSpotter auctions for your car. We're working on adding more marketplaces over time.
How do you know it's my car and not a lookalike?
Alerts are automatic, and only sent when the registration matches: from the advert itself, read from the number plate in the listing photos, or on AutoTrader from the partly hidden plate together with the car's make, model and year. A lookalike on its own isn't enough.
Still thinking about that car?
Most listings sell within days. We make sure you never miss your chance to buy it back.
