Jerry Seinfeld just proved once again that he knows his way around a Porsche collection.
His 1971 911S, a car he handed over to RUF back in the day for a complete ground-up rebuild, just sold on Bring a Trailer for $657,000. Not a bad result for a machine that spent three years in Germany getting the full treatment.
For those who’ve followed Seinfeld beyond the sitcom, his passion for cars is legendary.The man owns a Carrera GT, a 959, and even got his hands on the Porsche 917K that Steve McQueen drove in the 1971 film Le Mans.
He’s not just collecting; he’s genuinely invested in automotive history and precision engineering.
His web series Comedians in Cars Getting Coffee showcased this obsession with everyone from Barack Obama to fellow comedians, illustrating that his car knowledge runs deep.

Seinfeld treats his Porsches like art pieces meant to be appreciated and driven, not locked away.
The story here is pretty straightforward. Seinfeld bought the 911S in 2008 and immediately shipped it to RUF’s Pfaffenhausen headquarters.
The specialists there basically dismantled everything, reinforced the chassis, stripped it to bare metal, and rebuilt it into something that respects what a 1971 911S was while being infinitely better at everything. That’s the RUF way.
The Gemini Blue Metallic paint stayed original, which was the right call. At first glance it looks stock. Look twice and you realize almost nothing is.
Under the decklid sits a 3.4-liter twin-plug flat-six that makes the original 2.2-liter sound like a golf club. Electronic fuel injection, individual throttle bodies, red velocity stacks.
The power runs through a custom six-speed manual gearbox with hydraulic clutch. Nothing about that existed in 1971. Bilstein suspension, G50 rear torsion tube, 930-style disc brakes with drilled rotors.
Satin-black Fuchs wheels wearing fresh Pirellis. That’s how you blend old and new without pretending.

The cabin mixes vintage authenticity with purposeful modern upgrades. Pepita cloth seats sit next to modern RUF gauges, while a Blaupunkt radio complements lightweight door panels that keep weight down without sacrificing that period feel.
Just 2,300 miles on the odometer since the rebuild finished. The car spent nearly three decades with one family before Seinfeld grabbed it, bringing with it solid provenance and a clean title.
This is the sort of car that justifies owning a massive collection. Not because of the celebrity attached to it, but because it actually represents something real. Seinfeld’s always been serious about that distinction.
He doesn’t just buy Porsches for the thrill of it. He buys them because they mean something, whether that’s engineering excellence or historical significance or pure driving pleasure.
A $657,000 sale price for a rebuilt 1971 911S proves the market agrees.
