Asked this question about MY body, wifey said Ferrari - and when I said, "Please! Objectively!" she said, "OK, a BMW 2 seater". Obviously biased, as you'll agree when we all meet. So I'm thinking about it myself, and I'm having a really difficult time. I'm thinking maybe Acura Integra with about 140 horses, on a really good day - not quite a sports car as such, but with aspirations thereto. Otherwise, Honda Civic - not the cheapo, not the hottie, just the average mid-grade one. It works, it's not very large, it's not un-fun, unless you've driven the Acura Integra and know better.
But my bod does something a car CAN'T do: Enjoy feelings and have a hell of a good time!
