When I showed a friend a pic of a white GTS Mustang he thought it looked like it was from 2001 A Space Odyssey. He'd never seen one before and he used to dabble with Victa 160s in go carts and even a bike!
The cover is light and flimsy when you hold it in your hands. It's a very thin veneer indeed. I do think they put in well thought out vents in the right places for good cooling and they even included a black plastic piece around the carburettor and fuel tank to prevent debris from getting in.
There's also a fancy looking metal box concealing the muffler, screwed to the deck, to act as a heat shield for the plastic cover.
