Best starter car in NFS Carbon?

I feel the need to ask this question in preparation for the day I would play NFS Carbon on my PC.

Carbon has three starter car choices: the Mazda RX-8 (Tuner), the Chevrolet Camaro SS (Muscle), and the Alfa Romeo Brera (Exotic).
For me, the Alfa Romeo is already shelved since I heard frequently that it is the worst car to start out with. That narrows the choice down to two: the Mazda and the Chevy.
Which of these two would be the best choice for a player like me, who has never played NFS Carbon before?
