Why a used BMW? Just for the status symbol?? Just want to know why?
I would seriously look at the G35 - I have been, with a little but of drool.. If you like Jap cars then thats a nice one, there a quite a few nice ones.
Audi is also a considerations, even more so if you are in any snowy environments. Subaru fits this bill as well...
Well its your decision, go test drive a few, each car is different and every one like some different, given thats why there are so many car makers...
