Both Audi and BMW 有點招搖, but if you consider Audi

I highly suggest you do some research about the post-sale service on Audi. I heard some not-so-pleasant comments about Audi... I personally care so much about post-sale service because you do have to take your car in for some warranty stuff, oil change etc... I have friends who own BMW and agreed that once you have it, you can't let go of the fun. But again, is a little 招搖 as you said. I would go for Acura TSX or TL. Well within your budget, luxury but not so 招搖.
