Anyone have any opinions on what they would get and why?
I'd only buy one if it was a manual, and the A4 would be a 1.8T and a B5 generation (don't like the looks of the newer B6).
The URS4 is a piece of Audi history, and it would be amazing to have one with a decent exhaust on it to hear that legendary 5 cylinder howl.
The S4 is obviously the pinnacle of the audi "4" line, but that comes at a price premium that may not be worth it. I already have a couple of (actual) race cars, so I don't need something ridiculously fast for the street, just something that can be made to look good in the summer and DD in the winter.
