I found a few nice e93's in various colours and options for 25K, quite a few engine options too (although the 330d seem popular). The only concern from the wife was getting stuck in the snow as I have done with my e92.
I think the bigger audis (A4 / A5) would look like she has borrowed my car. The TT I thought was a good female choice but the lack of 4 seats means we would use it less.
If it was my choice I'd probably go for a Z4 convertible with the folding metal roof (again only 2 seats) but looks nice. I'll look around at the used Porsche sites as it might be easier to just get another one and find some extra cash.
