There are ways to do it
It looks like tracking down that cool ride you once owned just got a little easier, maybe. AutoCheck (a part of Experian) now offers a service to help track down a vehicle you may have owned previously by providing the last known area the vehicle was registered in. Sounds like this site is what Car Domain could have been, it’s part social networking for vehicles, vehicle tracking, sharing your personal vehicle history and using AutoCheck® vehicle history reports to discover the service history of a vehicle you are looking to research.
Another way would be to join a social network for car fanatics
this would mean that you would have to tell the people on the site what town you lived in when you sold it, a bunch of pictures of the vehicle when you owned it, etc
Personally, i would be looking for a vehicle that someone had started fixing up & is short of funds, so they can't finish the project.
