Jerry Seinfeld’s car collection is the stuff of legend, but few pieces speak to his taste for precision quite like this. His RUF-modified 1971 Porsche 911S coupe has appeared on Bring a Trailer, with bids already passing $500,000 ahead of the auction’s close on 16 October.
Seinfeld bought the car in 2008 and sent it straight to RUF Automobile in Pfaffenhausen, Germany, where it spent three years being stripped, rebuilt and re-engineered. Beneath its familiar long-hood silhouette now sits a twin-plug 3.4-litre flat-six with individual throttle bodies, electronic fuel injection and a RUF exhaust system, producing around 340 horsepower. Power is delivered through a custom six-speed manual transaxle and reinforced chassis fitted with a G50 rear torsion tube, RUF Bilstein suspension and 930-spec brakes.


The car retains its original Gemini Blue Metallic paintwork, now refreshed and subtly widened with flared rear arches. Details such as Fuchs 15-inch wheels, Euro-style lighting and a power sunroof keep it authentically ’70s, while modern refinements – thermostat-controlled RSR oil coolers, drilled rotors and RUF-branded calipers – underline the tuner’s obsessive attention to detail.


Inside, black leather and Pepita cloth cover the sport seats, the rear bench has been deleted, and the lightweight door panels nod to the racing heritage. A period Blaupunkt radio remains on the dash, framed by a RUF-branded 10k-rpm tachometer and VDO gauges showing just 2,300 miles since the rebuild.


It’s a car that sits somewhere between restoration and reinvention – classic form sharpened by engineering rigour – and it neatly reflects the instincts of both RUF and Seinfeld: understated, exacting, and entirely about the drive.
