Oh mate you're not getting it. The GPs ALL had identical fonted roof numbers - this is how they were supplied in 2012/13. They were not added by owners! Very unlikely 500 UK owners went out to get exactly the same roof stickers lol. I think you guys here have got your fact wrong.
No mate - you have yours wrong. The cars didn’t come with a roof number from the factory. Only in America. Any numbers on the car in the UK market were added at a later date. They were not part of the launch specification and they did not leave the factory with them. Even in the USA they were applied by the dealers.
I’m not trying to be funny, I’m just trying to point out the facts. I know these cars, I’ve had two GP1’s.
