I'm a recent college grad (graduated last year). I didn't have a car on campus and didn't really ever need one at all (I commuted by train 5 days a week), so my situation isn't the same as yours.
Still, I agree with the others - hold off on getting something expensive until you can afford it (i.e. after you get a job and graduate). Once you've used up all of your money buying the car, are you going to be able to maintain it and putting gas in it? Based on your OP ("I'll be a poor college student without many car skills") I have a feeling the answer is no.
Buying a beater (or an older used car) is a much more responsible financial decision, and it will make you appreciate whatever nice car you might buy after college even more. Besides, if you're only driving 4k miles a year (which is nothing), you won't have much time to enjoy a car like a G37 as it drops in value like a rock. And you won't get upset when someone puts a door ding on your 10 year old Civic (or any number of other safe, reliable older cars).
