This week's episode had a commercial for next week and it showed the track in action in their warehouse, the viper rolling down the hill in South Lake Tahoe, the toy car racing down my track, and also their custom cars. That is around 50 minutes into the program. They also showed a JL car which I think was a Mustang.
Also, during the episode, in the warehouse, Adam walked by a ramp and I recognized my track laid up on it

It is around six minutes into the episode.
Tonight's episode will repeat Sunday at noon in California. You'll have to check your local listings to see exactly what time is in your area.
