thnx 4 all the info, yeah i think your particular x5 is a lemon. well, have fun with ya 911, both are great cars. since you are in toronto, i can only think of these dealers:

bmw of toronto
parkview bmw
town & country bmw
budd's bmw

i suspect it is either T&C or budd's. i went to T&C for a test drive once and the salesguy was like a mute, didnt even attempt to sell me a car.

one member here was saying he had a nasty experience with budd's regarding the 3m scotchguards.

of course i'm only speculating.
