I went into to this dealership to learn a bit more about BMWs.  I'd just come from across the street at Audi and had test driven the S5 there.  My wife wanted me to test drive the M3 as a comparable car that her colleague had.  The sales person came up and asked us to what we wanted and we explained quickly.  He then went on some long tirade about how the M3 was only for \""car enthusiasts\"" and wasn't for us.  So then we asked to test drive a 3-series.   After disappearing for 20 minutes he says excitedly that he has an M3 on the lot. Wonderful.  He then goes and pulls up the M3 and proceeds to tell me that we can't test drive it because it would \""ruin it for other people.\""   At this point, my wife and I walk away.
