So far I see a lot of cars that have specific trim levels specified. A non-turbo MR2 and a turbo MR2 would be the same as far as the question is concerned. This was about looks, not performance.

So a Integra Type-R is no different from a 4 cylinder Integra of the same body style. A turbo Supra is no different from a regular Supra. Etc.

That said...I'm Mazda biased. Miata, RX-7, MX-6, etc. I like Mazda's sporty car linup more than any other manufacturer.
