I think I'm qualified to express my opinion since I've owned like 80% of the cars recommended so far.
I know most wouldn't consider it because they are too concerned about image, but Dick has a point, a Mustang is not such a ridiculous choice. Two years ago I wouldn't have dreamed of it, but the fact of the matter is I've had one for six months now and couldn't be happier. The car is an absolute hoot, I have fun driving it every minute that I'm driving it. Most fun car I have ever owned, and my credentials are pretty decent. MkII and MkIII Supras, SE-R, GTI, DSMs (plural), MR2s turbo and N/A. While its not perfect, there is something inherently good about 300 ft-lbs of torque and RWD in a car that is not too incredibly portly. The handling is not razor sharp, but that also means you cut yourself less.

And anyone who would consider daily driving an Expedition can't really complain about the handling of a Mustang.

I guess the best defense I can say for the Mustang, is my MR2 turbo is sitting around collecting dust and the miles are piling up on the Mustang. Whodda thunk it??
Just FYI, my co-worker with the '96 SE-R said he would let it go for $3K
