I have the receipts for most of the parts and the maintenance records as well, however the last few oil changes I have performed myself. Currently running royal purple full synth w/ a hamp filter. By maintenance records I have the receipts for the oil changes, and for the parts put on by the mechanic have had no other maintenance issues(only 44K). BTW i forgot to add I have a video I could send to your email of the car: starting, ideling and the exhaust sound, if you want the video and more pics pm me your email address.
