What kind of sports car should i get?

Hello, i am 18 years old and my parents are going to help me buy a car as a grad present. i am going to college and going to be taking a loan out for the car. dont say you shouldnt get a sports car because your 18, im not dumb. im going to college and going to have a good paying job after. btw college will be paid for in cash so dont point that out either, i worked ALOT as a senior. anyway just get me some input. i like the 350z's and stuff like that, no mustangs or supercharged cars, theyll make my insurance too high. haha. so gimme some ideas and some input. max price about $25000. thanks
