Plot: Scrapyard Kings is what happens when Heavy D (Dave Sparks) and Diesel Dave (Dave Kiley) toss Junkyard Wars, Top Gear and a box of welding rods into a blender. Each episode drops three rival teams into a massive junkyard, hands them a shoestring budget, and dares them to cobble together machines that can rip across land, skim water —and, when chaos cooperates—leave the ground entirely, all under the Davids’ wise-cracking supervision
