In regards to the 40th Anniversary GTO.
I hate to burst the bubble here but this is not it !!
There will be a 40th Anniversary GTO model and it'll be released in the near future.
It comes in a new colour called Pulse (Mid Red) which will only be available on the anniversary model, it also has Black Leather with 40th Anniversary embroidered into the front seat covers. Other than that there's not much difference.
