No you guys were not in it.
How does this idea of redoing the rear (window back) sound? So that there would be twin exhaust stacks and a sloping back with a fake 'fifth wheel' on it. Tires open with a large mud flap (naturally).
If that doesn't sound cool...................... how about a fake tow truck 'boom'?
Not sure what I ate, but the idea is growing on me.
