“Each example has been individually named for its commission, which is embossed on the door sill along with script reading “Limited to 1 of 25,” a permanent record of the car’s unique identity."

They said that the work on the 911 cost £619,605 before delivery fees, including £166,170 for upgraded equipment.

“In commemoration of the Carrera-based boutique model, the striking car was displayed by Gunther Werks at The Quail: A Motorsports Gathering in 2022, where it debuted to overwhelming acclaim.

“Since then, the original owner has kept the 911 fastidiously garaged and maintained in showroom condition," the auctioneers said.

“Showing signs of little to no use, this magnificent Gunther currently displays “delivery mileage.”

“For power, Porsche’s standard 3.6-litre flat six-cylinder engine is entrusted to Rothsport Road and Race in Sherwood, Oregon, where it is stripped down and enlarged to 4.0 litres of displacement."

“The happy result of these sweeping upgrades is a significant boost in power, as the Rothsport engine develops 435 horsepower while generating 312 pound-feet of torque."
