These cars are simple. If you undertake a car project, this will have the most basic suspension, frame, drivetrain, body, wiring and accessory combo of just about anything that can be driven on the street.

Consider it a small 2 room cottage. You still have a roof, exterior walls, wiring and plumbing, interior walls, floor and basic appliances, so you will need to be able to work on each of those. But the amount of work is less than the same work on a 3Br 2Ba split level.
