By 1988, nearly two decades after its stunning 1971 Geneva debut, the Marcello Gandini-designed Lamborghini Countach had become one of the most iconic supercars of all time. To commemorate the marque’s 25th anniversary – and the Countach’s finale – Lamborghini unveiled its most developed version, the 25th Anniversary Edition.

The new model retained the 5000 QV’s underpinnings, but received extensive updates overseen by Horacio Pagani, then a rising engineering talent at the company. The bodywork was revised with reshaped bumpers, deeper side skirts, and enlarged air intakes to improve cooling. Composite materials were used for the spoiler and the cabin offered better ventilation, more supportive seats, and enhanced fit and finish.

Power came from a 5.2-liter, quad-cam V-12 and US- and Canadian-specification cars produced 415 hp. It could reach 0–60 mph in approximately 4.7 seconds and a claimed top speed of 183 mph.

This 1990 example is finished in Rosso Siviglia (Seville Red) over Champagne leather with red piping and was delivered on June 22, 1989, to Lamborghini distributor Eugene Carrie, according to factory data provided by legendary Lamborghini test driver Valentino Balboni.

According to the consignor, the Countach is believed to have been specially ordered without Lamborghini’s iconic but optional rear wing, by Wallace J. Sulentic, a manufacturing executive and enthusiast. In correspondence on file, Sulentic explained, “I wanted a car without a rear wing…I wanted a car exactly as it came from the factory.”

Sulentic retained the Countach and kept it unregistered and on its Manufacturer’s Statement of Origin (MSO) until December 1996, when he titled it and sold it to Dr. Gary Groves, a physician and collector based in Redlands, California. A letter on file and accompanying photograph highlight that the Lamborghini had then traveled just 524 km (325 miles).

Dr. Groves, who maintained an impressive collection, used the car sparingly, and, in 2012, the mileage was recorded as just 1,339 km (832 miles). Groves kept the Countach until around 2014, at which point it was sold into a private collection in Ohio. In 2023, the Lamborghini was sold to the consignor, who, in 2025, had an oil filter change, hi-speed polish, show-level detail, and fluids change performed.

Showing just 1,526 km (948 miles) when catalogued, the Countach remains in remarkable condition, with countless original details throughout, and the consignor notes that the rear panel has never been drilled for a license plate. The car is accompanied by a tool kit, literature, factory brochure, period correspondence, and other records.

In a May 2023 retrospective on the Countach, Road & Track magazine noted, “It not only lives up to its outrageous looks – it also surprises as a legitimately pleasant grand touring machine.” Exceptionally original, fastidiously preserved, and offered with fascinating documentation, this time capsule Countach is one of the most compelling 25th Anniversary Editions to come to market in many years.
