Any good inexpensive sports cars?

[Oh no!]

I'm 21, and I'm in college. I currently don't have a car whatsoever, but i do know how to drive. Unfortunately the public transportation they have just for the university is pretty crappy. I'm thinking of getting my own car. I want manual transmisson for the first part. I learned on stick shift, and I've driven an automatic too, and I prefer manual for it's better control. The body style should be a four seater, (to transport my classmates.) two door coupe. As for where I'm going, the answer to that is, well, everywhere, the store, my classes, road trips, you name it. My budget is up to about $50,000. I prefer american brands, such as ford, Chevy, ect. As well as german sports car brands like BMW, and mercedes. I'm not sure about japanese brands such as toyota, They may not cut it. As for british brands, although they are expensive, they are so desirable! If there is good deals on maybe a jaguar that would fit my budget, that would be an honor. Italian brands, OMG, They're great. Although there's a 99.9% chance I'm not getting one. I need also a comfortable interior, a cd/mp3 player, a good ac (It gets so hot here, I need a good ac), a radio, and other miscellaneous stuff. I'll buy either new or used. But if its used, it has to be in good condition. I don't want it to be TOO much of a gas guzzler as well. That's about it. Answers needed.
