I'm looking into buying a new car and I've narrowed it down to these. Which one do you guys personally like?

Audi a4 hands down

which A4? 2.0T? If so then DEFINITELY the audi.

with the a4 you get significantly much more for your money, features wise, and arguably style-wise (esp 2009). BMW has the better resale value. re: CI vs XI - depends where you live. it's worthless in southern cal, but in aspen, it's imperative. I guess quattro would be imperative also.
