The Grand Touring Garage Trans-Cammer, frap frap fraaaaap blurb warble worble LOVE IT. It also has massive low end torque so you can keep it down low revs and enjoy that grumble even more. And it looks so mean, just wish I could get white racing stripes and tires with white font on it, that would make it perfect.
I really wish there was a more pronounced tunnel reverb, going though a tunnel there's hardly any change in sound.
The Art Morrison Corvette and the Shelby Cobra are not half bad either.
