A junky, wothless car that the owner had put money into that only makes it look worse. Or even comical. Examples would be spinning plastic hubcaps, a fin, offroad tires, and a cheap stereo from Value City that will be stolen soon because the window will not roll up.
What do you mean that's your G Ride? That's just a hooptie.
An old, ugly car that still runs.
Man, that 1979 Cordoba with the dent in the side is one hell of a buckit!
