I am the 6th owner of my 1981 Trans Am. My car is a bit of a whore. It has been registered with each owner so it has (probably) been on the road in some fashion with each of them. It had at least 141,000 miles on it when I got it (odometer stopped working on the 41,000 mark but It was registered once at 98,000mi). I think it is safe to say I have one of the highest mileage examples of my car that still exists.
