Scorchers themed track set originally sold in stores. This track comes with a Highway 35 Muscle Tone variation (not the official vehicle however).

This track had a lot of potential, but so far I've not been able to get a car all the way through the track. The whole thing is kind of wobbly and there's not much clearance as the car enters the loop. Still, with some modifications, I think it could work. Its also a cool looking track if nothing else.
