. It was nice to see every oil changed and when they were done/mileage, and those things I trust since they're entered into the record by the shops, but it seems like I might have passed over a few cars that showed damage that may not have had any.[/QUOTE]
Well if I ever sell my Z, Carfax will show the last oil change in 2016 (or anything for that matter).
I do all of my own maintenance.
