For the "recording purposes" my indy mechanic does not release the info to carfax.
So if I ever did list the car, the carfax would show a service history for the car right around when Inspection I should happen and help to verify that at least something was done during that time.
I do keep a book of everything ever done or purchased for the car, from oil changes to alignments to the zhp shift knob.
However, someone buying a BMW may think that using the stealership is better than the indy mechanic (which we know is not true). So for the BIG services, it's nice to show "service by BMW of ..."
Looks like I will just get an oil change and enjoy the car until the middle of next summer when I cross 30,000 miles!
