I'm looking to either buy or lease a 2006 Audi A4 2.0 or BMW 325i Sedan.

Any recommendations? I really like the look and feel of the Audi but have read that the BMW is a better more solid choice.

If you have to ask, you should get a BMW like everyone else. If you already know better and can appreciate style, luxury, convenience and performance over status, Audi. New A4, especially with the 3.2L engine, is better than any 3-series except of course the M3. And I'd say it's better than the M3 if you'll be on anything short of perfectly dry road conditions.

You should really test-drive them, for BMW has trimmed its chances against Audi´s Quattro with their xDrive awd.

BMW. It's rare that the 3 series disappoints.

The Audi is nice, but the BMW is a better car, if for no other reason than resale value. Other cars to consider: Volkswagen Passat (same 2.0 engine as the Audi, much the same platform),and the Infiniti G35 (will blow away a 325i for less money, and much more reliable).
