Does it really matter?
All of these upside down bathtubs are almost identical, except for the paint anyway.
Show someone on the street (you know, the people who you are trying to attract) any of the current body styles in primer, and ask them to point out which make it is..

It may as well be a Jeep Wrangler. They'll still shape it the same way as the rest of the FC bodies, with different headlight and taillight paint.
Man, I would LOVE to see something different. Something more real, like a Vette that looks like a Vette, or a Camaro body that looks like a Camaro.
