Aha, finally a car I'm familiar with!
This car has many faults: It's rare. Seems odd that GT included it and neglected the original Beetle. The tires suck, no matter if you're using slicks or not, the rear-engine design makes it hard to manuever. Of course, the power REALLY sucks.
On the plus side: It's low in cost, has 2 engine modifications available, it's the lightest car in the game, and will fit thru traffic others would dare not go. Plus, there's the novelty factor.
I give it 40% out of 100
