Both are great cars but I lean towards BMW because its handling is simply unmatched IMHO. The Audi does have AWD however which many people prefer during ice and snow season.
Audi has drastically improved their overall quality in recent years as well. BMWs are hit and miss: you can have a wonderful vehicle that never has any problems for years, or a rolling piece of headache that's in the shop a lot, at least it appears to be that way. Luckily the BMW warranty should take care of it.

If you haven't already done so you'll really want to test drive them both. The handling is different, and the BMW picks up a lot quicker and seems to have slightly better stopping power.

Edmunds.com and other review sites may offer a little more detailed help as well.

Good luck, no matter which one you go with, it'll be a good choice :)

Kroyrotica - very nice post, what you said about "hit-or-miss" with BMW also applys 100% to Mercedes (specialy their Diesel models)

between those 2 i would say Audi A6

i don't care for bmw so i'm suggesting the audi

BMW of course

Thank you all for wonderful posts! They help me a lot. For example I have learned that BMWs break down a lot..which is something I didn't know before. :)

believe me, audi is worse then bmw in terms of reliability... go look at the statistics

Mmmmm that BMW looks nice and juicy.

I'd go for the BMW. It has more curves to it.
