1975 Porsche 911S Coupe Silver Anniversary Edition

Exclusive to the 1975 model year, the Porsche 911S Silver Anniversary Edition celebrated 25 years of Porsche sports car production as the marque’s first commemorative models.

Each was finished in Diamond Silver Metallic over unique leatherette and tweed upholstery with additional distinguishing details. This 911S Coupe Silver Anniversary is designated #427 of 1,063 examples produced, of which only 504 were reportedly brought to the United States.

Originally acquired on November 28, 1975, it remained with the first owner in Illinois before being passed on to their son, and later to the current owner in April 2023. Showing under 168k miles, this rare example is now being offered for auction out of California.
