knowing what you know now what would you have done different.

Well since we're talking about any regrets... I should have kept playing with computers in middle school instead of screwing with cars.

I could have been one of those dot.com millionaires and bought a Lamborghini at 22, and been bankrupt by 26!

Automotive regrets? The ragtop Nova for $2200, the 65 Chevelle SS for $2000 (passed on that one because it was a powerglide, the car was perfect otherwise) or the '33 Ford 3-window for $3000 are at the top of the list.
