Back when I had my formal, I unexpectedly ended up going in a 68 Camero at the last minute through the parents of a friend. I think it was the best looking car there, although them being obvious GM fans I had to put up with a bit of Ford slander, but other than that the ride was fantastic. I know others decided to be funny and show up in vehicles like a Kenworth truck and a cardboard box with wheels painted on it.
