I have two shows that I can't remember the name of.
1. mini series on abc 80's-90's teenagers pilot a ship from earth to find a new planet and I think colonize, they end up uncovering a rebellion. May have been made by Disney.
2. 80's. A family take a tour of a pyramid and gets left inside in an inner room. They are then transported to another planet. It had 2 scifi cars (cars pic http://www.snowcrest.net/fox/landmaster/pics/car5.JPG) made by Dean Jefferies. Think one of the cars was also in logun's run. Remember something about zone's and zone troopers.
