While functional, a jankbox is a four wheel vehicle, most typically a truck (but not exclusively), which appears to be on its last axle, contains multiple vehicle parts that are not original to the whip, and sports a mix-matched paint scheme.

Origin: the origin of "jankbox" is to words what jankbox is to vehicles. Jankbox is a compound word with (i) jank being derived from janky, a combination of the English words skanky and junky that describes an item of inferior quality, and (ii) box being derived from the English word "box" and slang for vehicle.

I have 6 jankboxes hidden from my wife in the barn for hauling equipment.

I may have a jankbox, but at least I have a car.
