The stock ’73 Porsche 911S sold for $151,200 that seems about normal while the Brumos 911S sold for $280,000, more than a $128,000 than the stock 911S. Is the Brumos history worth this much? Let’s look a the spec for each car.

The Tale of Two Sales

The two cars sold at the same Gooding & Co Amelia Island Auction. A premium of $128,000 seems like a giant premium for Peter Gregg and Brumos provenance, but it is one-of-a-kind in Porsche history and sold in the Jacksonville area; home to Brumos and Peter Gregg. I believe the buyer paid all the money for this car, plus some.


It was noted on Facebook that this is the new owner’s first air-cooled Porsche for his collection and he intends to use it. References were being made to show it at Luftgekühlt 7 being held this Spring in Durham, North Carolina. When you are dealing with owners who can spend $200,000 plus for a collector car, the rational buying decisions often go out the window. In this case it sounds like the new owner wanted to gain entry to a prestigious event and wanted the bragging rights of having this unique one-of-a-kind car.


The Silver Porsche 911S was actually sold a little low according to the Sports Car Market Price Guide that states the median price for such a car is $178,000. In this case the new owner bought a very nice, clean, well-documented 1973 911S that can be driven, shown and enjoyed without regret.


Gooding & Company Catalog Description of the Peter Gregg Brumos Porsche 911S

In the decades since the untimely passing of Peter Gregg, much has been written about his rare driving talents and sharp business acumen. In the early 1960s, Gregg began his illustrious professional racing career and his accumulation of automotive dealerships almost simultaneously. Most notably, he acquired Brumos Porsche in Jacksonville, Florida, in 1965. Behind the wheel, Gregg posted an incredible list of victories, including multiple championships in SCCA, IMSA, and Trans Am divisions and three Overall wins at the 24 Hours of Daytona.

In late 1972, Gregg hatched a plan to create a very special 911 S to serve as his personal road car. In keeping with Gregg’s notoriously exacting nature, all modifications made to his car by his Brumos service department were to be in consultation with and approved by the Porsche factory, and strictly limited to the use of Porsche factory parts. Porsche took careful notice of the project and incorporated many of these upgrades into future models.


The building process began with the addition of Carrera RS steel flares and modified rear bumper, with the Porsche Racing Parts Department supplying a ducktail rear-deck spoiler. In front, the bumper guards were deleted and then-exotic Cibiē quartz-iodine headlamp units were added. Handling was enhanced by Fuchs 15″ x 7″ and 15″ x 9″ wheels as well as larger sway bars and stronger stabilizer bars. As a finishing touch, the famous Brumos stripes, largely of Gregg’s own design, were added to the silver S, bordered in white. This 911 S was the first road-going Porsche to wear these iconic stripes.


In 1974, Gregg sold the Porsche to a long-term client, who traded it for his 916 and retained the car until 1979, before selling it to a friend and colleague, who drove it approximately 80,000 miles as his daily transport over the next seven years. Then in 1987, showing over 130,000 miles, it was reacquired by Brumos and treated to a thorough bare-metal restoration to its original specifications. At this time, the windshield wipers were modified to park on the right, matching the specification of Porsche racing cars of the period.
