I worked a car show one year and was talking to the AM guy who was there with a Vantage Roadster. I asked if he was by any chance he was bringing a One-77 as well. He said he doubted he would ever even see one let alone bring one to a car show....and he was a dealer!
There are only 76 now. One was wrecked. Lexus made 300 LFA's and I'm pretty sure there's more than 300 Veyrons on the road. The only thing rarer, I think is the Hennessy Venom they are only making ten per year and Lotus isn't doing the Elise anymore. It's the car that Venom is based on.
