Car Buying Question

Hey everyone, i'm a 20 year old college student who stays home for school and works. I am looking to finally buy a new car and i am just having some trouble deciding which which way to go. I want a fast car, but i also want something that i won't mind driving for the next 6 years or so. So i would like a nice, comfortable interior. I've been thinking about older evo's or STi's however they are a bit pricey and the interior is nothing to brag about. My friend owns a Cobalt ss/sc and i think its a great car. Clearly i'm not looking to get the same way but i love the combination of speed and the nice comfortable interior. The whole interior is just nice from the seats to the stereo(he has the XM radio upgrade). So I have given thought to waiting until the "2008.5 turbo cobalt comes out the only problem is nobody has a real answer on when it will be released. So i also thought about g35's and 350z's but i don't like the idea of a 2 seater and i was leaning more towards a car that was not N/A. So basically what i'm saying is i am looking for a car that has a fair amount of both speed and comfort. I think right now the front runner is the g35 coupe.

Any ideas? or comments?

Grand Prix GTP - GXP, Dodge Charger R/T - SRT8, G35 of course, Mustang GT, New Camaro, Saab 9-3 Stick, Idk Caliber SRT?

What is your budget?

my budget is no more than 25k but i'd prefer for it to be around 20 if possible

How about an Audi S4? It is damn fast and you got that nice Audi luxury. Invest in Audi aftermarket performance and you'll have an STi killer.
