How to find a specific car style?

I am looking to buy a car in the somewhat near future and I am having trouble deciding which car I want to purchase. I know I want a coupe. But that's all I know for sure. Is there some sort of site where I can pick out specific car body style features and it will give me the closest matches? Or a "design your own car and we'll tell you what cars are out there that look like that" type deal? Thanks =]
