The Lamborghini Countach is a mid-engined, V12 sports car produced by Italian car manufacturer Lamborghini from 1974 to 1990. Its design pioneered and popularized the wedge-shaped, sharply angled look popular in many high-performance sports cars. It also popularized the "cab forward" design concept, which pushes the passenger compartment forward to accommodate a larger engine.

This die-cast model is based on the LP400 S model, released in 1978. Though the engine was slightly downgraded from the previous LP400 model (355 hp (261 kW)), the most radical changes were in the exterior, where the tires were replaced with 345/35R15 Pirelli P7 tyres; the widest tyres available on a production car at the time, and fiberglass wheel arch extensions were added, giving the car the fundamental look it kept until the end of its production run. An optional V-shaped spoiler was available over the rear deck, which, while improving high-speed stability, reduced the top speed by at least 16 km/h (10 mph). Most owners ordered the wing.

Early castings of the die-cast model have the wing molded separately from the body. There must have been assembly or tool and die issues, because the wing was later integrated into the body, making it one piece.
