I'm a Corvette...

...or as the results page puts it:

"You're a classic - powerful, athletic, and competitive. You're all about winning the race and getting the job done. While you have a practical everyday side, you get wild when anyone pushes your pedal. You hate to lose, but you hardly ever do."

If I change the answer to the question I had trouble answering, I become a Lamborghini Murcielago.

Which sports car are you?
