I don't know boys. We have not learned much detail on the Motion SuperCoupe, but if you look at the engineering involved in Time Machine's Six Shooter 'cuda, the competition may be closer than you think.

I'm not trying to be a Mule heretic, I just think we're entering a new era where full frame cars with engine setback, channeled bodies and 4 wheel independent suspension will dominate.
As for thrashing the Johnson 'Cuda: If one can afford the entry fee, then one can afford the repairs.
