I came across this link. I am afraid it only works for UK registered cars only.
Go to
http://www.rac.co.uk/myrac/vehicle_d...go.x=17&go.y=9 and enter the reg number of either your current car or a car you used to own. It will show you the following details
Manufacturer
Model
Body type
Colour
Fuel type
Date manufactured
Number of previous owners
Last owner change
i tried it on my past 3 cars and it came up will all their details bar one. The one it could not find has been written off so I suppose if you get no results the car has gone to Auto Heaven.
