Also a former Audi owner and lover... I think comparing the X and the Avant will be tough in a direct comparison, both are great vehicles in their own right.

Test drive the different motor options to find one that suits. I have found the Turbo 4's to be much more enjoyable then the 6's. I did however HATE the 2.0T with the 6 speed manual. it seemed to me the lower gears were too tight together, prompting WAY too many shifts in town. The 5 speed manual was much more to my liking

just my $0.02 plus tax
