The current A3 is very different than the A4. I bought mine after I saw it in person. I didnt even know they had brought it to the US. I think its a great car and is very practical with the hatch and folding back seat. This is something the A4 sedan does not have. Sure the seat folds but you cant really put stuff in it the way you can with the hatch.
Like I said, if they dont bring it in I will just buy a GTI or a Mini Cooper Countryman. Not a big deal though at the rate I keep my cars I figure its got at least 10 more years before I think about buying . I have a VW Golf thats 22 years old and is still streetable .
