The Countach 5000 QV, known as Quattrovalvole, is widely regarded as the most influential iteration of the iconic Italian supercar. Its V12 engine was enhanced in both size and power, with the addition of 4 valves per cylinder, hence the Quattrovalvole moniker. This model was also the first Countach to be fully homologated and type-approved for the U.S. market, paving the way for Lamborghini’s success in the region. It is estimated that fewer than 50 QV cars were produced with the side skirts and updated automatic climate control, known as the “1988.5” model year cars, including the one in question.

This particular Countach was originally delivered to Joe Nastasi, an official Lamborghini U.S. importer based in New York, in January 1988 and is one of nine Countachs delivered in Giallo Fly. The Lamborghini Registry confirms that this car, with chassis number JLA12300, was equipped with engine number 1514 which corresponds with the engine number that resides in it today. Additionally, this Lamborghini underwent a major engine-out service in 2021 by Auto Kremer, which included the installation of a new clutch, valve cover gaskets, and a set of 4 tires.
