In the late-1960s, George Barris made bolt-on customizing kits for the AMX that were marketed through AMC dealers. He also performed a radical custom treatment on a 1969 AMX. The car was built for the second Banacek TV season episode. The car was lowered and its body was heavily modified. Its roof was cut down almost 5 inches and the car was lengthened by almost 20 inches. Featuring a sculpted body with louvered accents, it became known as the AMX-400. The car featured a taillight system that glowed green during acceleration, amber during deceleration, and red during braking.
