First 1982 Lamborghini Countach found in storage, now for sale

After sitting in storage for more than two decades, the first Lamborghini Countach LP500 S ever produced has been uncovered.

The LP500 S nameplate marks the third version of the celebrated Countach supercar, which was manufactured in 1982.

Documentation reveals this particular example debuted at the 1982 Geneva Motor Show and was also reportedly used in Lamborghini brochures promoting the then-new LP500 S.

The listing claims this is one of the first five LP500S examples produced of the updated model's 321-car run, along with one of five early cars fitted with the “5L” logo (located on the rear).

The supercar was first purchased in Italy before being shipped to Germany. It then landed in the US where it was sold to Carlos Cavazo – guitarist for heavy metal band Quiet Riot. Paperwork reveals the car was then stored at Franco's European Sports Cars and remained there since 2001.

This Countach isn’t completely original, with modifications to the 4.8-litre V12 engine occurring in 1985. This saw the original Weber carburetors replaced for a fuel injection system, to ensure California emissions requirements were met. 

The vehicle does, however, include an unmounted factory rear wing, tool roll, spare wheel, service records, and an original owner's manual.

The listing says the supercar has about 65,000km on the odometer, but the current driving condition of the vehicle hasn't been described.

The unique Lamborghini LP500 S is listed with DriverSource in Houston, Texas, and priced from $US695,000 (about $AU1 million).
