I like the TSX a lot too. It's a great car, and I've heard that the auto isn't that bad. So why not a TSX? It's not like she'll be street racing. (I hope).
My SAAB 9-3 gets 25 mpg, with a 2.0 turbo, 210 hp. It's fast, faster than my X5 by a smidge. Although reliability sucks. The VW Jetta and Passat also have a 2.0t. There's also the Subaru Legacy, with out the turbo I think it makes 175 hp, AWD, auto, safe, etc.
