Just picked up my car ('00 m5) from Mountain View BMW (AKA Allison BMW). Took a close look at the car and discovered that the five (5) test-driving miles put on the car incurred SERIOUS tire wear!!!!!!!!!!!!!
Both front and rear (stock S-03's) tires showed very aggressive wear on the tire shoulder. This can ONLY be caused by throwing the car into tight corners: tire has to "roll" a ways for that shoulder portion to wear. Having already been familiarized with their "test course" when getting the car checked out, I know that it includes some pretty tight bends.
So, for all those owners posting stories of joyriding... I fully concur!!!

The test drive was done to check for the "bunny hop" symptom, NOT to throw the car around and possibly take it OFF the road. NOT only were the tires showing aggressive (i.e. coarse) wear, they were dirty as well: who knows, possible off-roading????!!!!!
In addition, the engine oil had been over-filled. Oh well, what can you expect. Apparently the dealership has more than enough business than it can handle. They NEVER return phone calls. You have to consider yourself lucky to get your car back period. They won't have to worry about my business again.
Could have been worse, one of the poor victims (errr... customers) before me had a nice 3 or 4 inch crease put in his driver's door: read "serious door ding".
Anyone know of a good privateer to service the Bimmerr at??? Also, what about parts where you don't have to go through the dealer???
