I've always wanted to sell exotic cars...I remember visiting a local exotic car dealer when I was young, just to look around. They let me sit in a Countach...I thought it was so cool.
They are still there too:
TEAM Motorsports | Sales and Leasing | Exotic cars
I think they only have a couple of sales guys, not a lot in the way of job opportunities. If I could do that for a living, I wouldn't worry about going back to school.
