We are not judging people by the cars they drive, you're not a douche BECAUSE you drive an Acura, its an observation that lots of douches happen to drive them.
Corvettes I agree with, but is mainly for the older douche.
Hummers, I only see women driving these.
BMW, obviously, but becoming too cliche, so the douche is branching out and winding up in the Acura.
To the guy that says he would like one of the cars mentioned but can't afford it - thats the part of the point. The douche can't afford it either, but unlike you, he goes and gets one anyway.
