That is not a 240z/260z window frame or roof line...


Real 250 GTO:





Replica 250 GTO (Obvious 240z door window frame and roof line and wrong door handles)





BUT since there were only 36 250 GTO's ever built with sales ranging from in the millions to $25 million USD. This is highly unlikely to be one of them. Companies have now figured out how to recreate the correct window frame. That rear tail is also molded incorrectly.
