I'm sure we all have stories about the dumbest thing anyone has ever said to you about your car. My recent experiences are:

1) Who makes X5? (Guy at the autoparts store Autozone, when i was getting a new bulb) I looked at him like he was retarded and said "BMW"

2) Who makes that? Toyota? (Guy at the auto parts store Oreilly, when i was getting a new battery) I paused for a few seconds thinking I heard something different, and I said " Uh, BMW buddy"

Nice to know that these guys have a clue huh?...Anyone with some other stories?
