Do you want something barely practical, slightly more practical, or very practical? New or used?
My old driver bit the dust late last year, and I tried to talk myself into getting some kind of fun sedan with perhaps a little bit of luxury, but then I caved and bought a used GT500. Mustangs might not be the greatest cars out there, but if you want something you can drive everyday and take to the track on occasion, without a ton of maintenance, they aren't a bad deal, you know if you don't mind Fords, or looking like a secretary
Otherwise there are G8s, G35 (which I would suggest, BTW), etc.
I'd suggest one to Todd, but he pretends to be a classy guy.
