"1975 Plyouth Duster" Model

I was at Hobby Lobby yesterday shopping with my wife and daughter, so I made my way back to the model section to pass the time. I spotted a model labled as "1975 Plyouth Duster Hardtop" I pulled the box off the shelf and started looking it over. It wasn't even a Duster it was a 1973-1976 Dodge Dart Sport, it had the Dart hood, grill and header panel, it even said Dodge on the grill. How can somthing like this slip by the people who make and research these modles. You don't see a Chevell sold as a Nova or a GTO sold as a Lemans. I still bought the model.
