TART BOX

Small, cheap car that has been modified--usually with scoops, vents, wings and alloy wheels-- to look faster than it actually is. Another ploy is to stick a massive exhaust on the car, ruining backpressure and performance, but making a suitably quasi-macho noise. Example: Darren had boyed up his tart box by putting neon lights on the underside. Consequently, everyone thought of him as a mental pygmy.
