I wish I could find it now... there was a great YouTube channel of several guys bodging together vehicles that were almost scrap from a field of abandoned cars and trucks. Lets find a frame from this hatchback... drop on a frame from a jeep... yeah, just run some rusty found bolts through the sheet metal to hold them together. Use some wire to tap on a dozen different batteries until you can find one with some spark... salvage some coolant from 3 cars in a gallon milk jug and add some puddle water to fill the coolant system... drain some gas into the same jug for fuel and presto! A running car!
Stumbled across the video I remembered. I particularly like the use of the doll's head as an oil cap.
