Har'har!searching on behalf of my client in Japan for a Mclaren F1.
not over priced
I believe ~$4M USD tops can easily get into a driven street/road version. By "easily" I mean if/when one ever surfaces on the market. . .I'm guessing they're pushing at least $7M these days.
That should be chassis #064. There is also a small possibility it could be #063 as we have kind of lost track of that one at the moment.
