I remember reading about that car in a magazine. I can't remember which one. Apparently, Ferrari doesn't lend cars to magazines for test drives, so they had to track down an owner. They finally located an Enzo owner in California. One thing I found particularly insane was the 0-60 rating. I think it was either 3.2 or 3.6 seconds. Someone correct me if I'm wrong.
At any rate, you were lucky to see one.
