You learn new things everyday if you listen and ask...
or sometimes people just tell you :P
Was told this by the youth of today how the luxury car you drive (if you are lucky enough to have one) defines you:
Mercedes - Sorry... doesn't matter what model it's for old people to drive.
BMW - For guys it means you're a "player", for girls it means you're a "kept woman" (not my thoughts i'm just passing them on).
Audi - successful, young an hot businesswoman (guess what car my "informant" wants to drive :P)
VW - once again sorry... no matter the model it means "you're not getting any!"
