I looked at the back seat of a A6 Avant (wagon I don't know if they call an A6 an Avant, just guessing) and it looked to have the same legroom as the A4, but was in the 50s so I think we will rule the A6 out. The A8 had a much bigger back seat but yeah thats not in our budget. She's always wanted a BMW 3 series, but I think the marketing towards younger people has worked on her and she seems interested in Audi and willing to check them out. I asked if she would look at the new MKZ (which I think is a total chic luxury car for some reason, and I think it looks great inside and out, I sat in one in Detroit) she said no in about .00005789 milliseconds, which by the speed of the answer tells me volumes.
