What Sports Car should I get?
The new mustang looks beautiful on paper, but it becomes an incessant nuisance in any cornering. The camaro is far too expensive for what you get. You only included american makes in your question, but the Mitsubishi Evo, Subaru Impreza wrx sti, and Honda S2000 each could beat any of the cars in your question. A 2 year old Evo with 40k miles would be about $25k, less than the GT, and I've witnessed that car walk on hundred thousand dollar italian supercars. Overall, go for a lightly used evo, for your money there is no better car, anywhere, to go fast in.
