4 models, 2 platforms (the Charger/Challenger/300 are the same plaftform).
If you want to get snippy about it, let's throw in the Ford Mustang and Crown Victoria, the Chevy Corvette, the Pontiac Sky and G8 (the latter made in Australia) and the Saturn Sky.
You almost could make a series with the Charger, Crown Vic and G8.
I'm not getting snippy...just pointing out the fact that it's not, nor has it been “stock” car racing for a very long time....they have pushed to sport towards marketing the driver “personality” as well as a circus atmosphere and they have succeeded....hence they should rename it National Association of Personalities Racing Identical Cars...NAPRIC
