I think the GT1 is replica, because i did some searching on that car, and i found one exactly like it for sale on ebay motors a couple years ago for $100,000 and it was replica one. With exact same wheels and everything.
I always stand in the middle where the cars go out and when i saw that that it was an omg!!! moment but now I hear its a fake….how disappointing cause its not worth faking the people out….anyway the crowd that followed it in to the pit area was pretty big
oh well maybe somebody will bring a real one someday…
