Do you have all the maintenance records & receipts? I assume all the work has been done by BMW since you work there. Also is there any warranty left by chance?
I wonder if he doesn't like it based upon working on it, or based upon modding it. I'm sure the average or even knowledge car guys/BMW guys would not have a clue to any difference (myself included). Do you plan on modding the car or anything? I'm thinking it wouldn't be any issue at all, I'm sure not worried about that, even if I decided to keep my car for a few more years. I have most of the receipts from service, definitely everything when BMW covered it. Some of the recent stuff like the water pump, oil change, brake flush, coolant flush, brakes, I've paid one of the senior BMW techs to do after hours. So it was all done by a BMW tech, but I don't have the "labor" receipts, just the receipt from the parts counter.
