Hmm. The coupe is better for you, because insurance on it is cheaper. If your a new driver, insurnace on this may be higher than your monthly car payment! since these cars are worth alot, and they are pretty fast, they are pretty hefty to insure.
The Coupe is a fun car. Its easy to handle, fun to drive, and good on gas. It is pretty simple to handle, becasue it doesnt have the idrive system, but it does lag in luxury at some aspects. As a first car, this car meets and exceeds the safety standards by miles. If you can pay for it, go for it! but let me tell you, as your fist car, this is not a good investment.
