I'm pretty sure that's not what Silas meant. He's a smart cat, and probably knows what a rotisseri is.
It doesn't matter if your car is on a spit, or saw-horses, or concrete blocks. Neither of those determine the final outcome, only quality craftsmanship really matters. I can think of more than a handfull of really clean cars here locally that didn't see a rotisseri. It's also not a new idea, it's already caught on, your bug is not the first car to see a rotisseri.
