[s-cars] Car advice

[Lee Levitt]

I'm starting to think about picking up another car, and I'd like some
advice.

First off, it WILL be an Audi, so lets get that out of the way :)

I'm looking for something that gets better gas mileage than my '99 A6,
something that I can both use as an every day commuter car and as an
occasional autocrosser and maybe track car.

I'm thinking about either an A4 or an S4 or possibly a TT. If its either of
the first two, I'd probably get an avant.

I'm looking to spend less than $20K. Obviously it will be used. 

Thoughts (reliability, fuel economy, years/models to avoid)?
