Chassis: 911 230 0538
Completed early in 1972, this ST 2.5 was sold to American racer Michael Keyser for his Toad Hall Racing team. He entered the car in the Sebring 12 Hours for himself and Porsche's Jürgen Barth. During the practice sessions the car was fitted with a camera for the legendary 'Speed Merchants' movie shot by Keyser about the 1972 World Championship. Starting 31st in the race, the American/German pairing ran as high as 11th overall five hours into the race but eventually they were forced to retire. Chassis 911 230 0538 was then shipped back to Europe and raced at the Targa Florio where Barth and Keyser finished 10th overall and second in class. They then finished 13th overall and 4th in class in the Nürbrgring 1000 km. At the subsequent 24 Hours of Le Mans, Barth and Keyser were joined by Frenchman Sylvain Garant. During practice the car was again equipped cameras for the Speed Merchants movie. As at the 'Ring, chassis 911 230 0538 finished 13th but this time, it was enough to clinch the GT class victory. Keyser returned to the United States and competed in several more races but he can not remember if these were run with this car as well. He did win the Mid Ohio 6 Hours outright with Bob Beasley and won the class during the Watkins Glen Six Hours, both with ST 911s. Keyser's final outing with presumably 911 230 0538 was the 1973 Daytona 24 Hours where he finished 8th overall with Bob Beasley and Tony Adamowicz.

Keyser replaced the ST with a new RSR 2.8 after Daytona and sold this car to Don Lindley. He continued its contemporary racing career and finished an impressive 7th overall at the subsequent Sebring 12 Hours, sharing with Steven Behr and Brian Goellnicht. Lindley would go on to race the car well into the 1975 season, with a final outing at the Riverside 6 Hours in May, where the 911 ST 2.5 was classified 32nd overall. Chassis 911 230 0538 was then briefly owned by Courtney Cranton before it was acquired by Garry DuHaime in 1976. He would go on to own the car for over three decades before selling it on to fellow American Marco Martinello in 2007. By that time, the car was in rather derelict condition. In the same state, it was acquired by a Swiss enthusiast early in 2013. He brought the 911 to Porsche Classic in September of that year for a complete restoration. The extensive work would take until February of 2016. Boasting the livery of the Le Mans class winning effort, the final result was shown for the first time at the 2016 Techno Classica.
