I drive an A3 3.2 V6 Sportsback with the DSG transmission.
It is a fine car, well engineered and the DSG is a good comprimise between an auto tranny and a manual. It is reasonably fast although it is not a rocket (I think it weighs more than my turbo) so do the math. I deleted the standard sport suspension to get more comfort but even with the sport suspension it is not a "sporty" car - not a hot hatch. It oversteers and due to the weight its not ideal for track events and twisties. I think the new S3 or the 130i would be much more what you are looking for.

I use the car as a pratical car next to my turbo (for "understated" city driving and as a transporter of bulky goods and people) and it does this job very well.
