Jerry Seinfeld is famous for his namesake sitcom and standup comedy, but to the automotive world, he's famous for a different reason, Seinfeld's impressive car collection. Avid watchers of his show will see posters of Porsches peppered throughout his apartment, and upon learning of his extensive car collection, it's blatantly obvious that he's possibly the biggest Porsche fan ever.
In 2016, Seinfeld sent several of his Porsches to auction, netting a total of $22 million, so he could share his love of the brand. He's certainly got an eye for the Stuttgart-based sports car. These are the most valuable types of Porsches that have ever graced his extensive collection.
10 1955 Porsche 550 Spyder - $5.35 Million
One of the most valuable Porsches in Seinfeld's collection is a 1955 Porsche 550 Spyder. Only 90 were made between 1953-1956, one owned by James Dean which lead to his untimely death near Paso Robles, California.
The 550 used an all-aluminum mid-mounted 1.5-liter flat-four with dual overhead camshafts and produced 110 horsepower to the rear wheels. Thanks in part to its curb weight of just 1,400 pounds, the 550 could hit 60 mph in just seven seconds and top out at 140 mph without breaking a sweat.
9 1959 Porsche 718 RSK Spyder - $3.7 Million
The Porsche 718 was the successor to the 550, and spectacularly rare. Only 40 RSK models were built, this time with the option of a bigger engine. The 718 could come equipped with a 160 horsepower 1.7-liter flat-four, while the-1.5 liter was bumped up to 148 hp.
Seinfeld's particular 718 featured the 1.5-liter flat-four and a curb weight of just 1,270 pounds. It was featured in several races, taking home two wins at the 1959 Daytona 1000 km and the 1959 Targa Florio, an endurance race held in Sicily from 1906-1977.
8 1973 Porsche 917/30 Can-Am Spyder - $3.5 Million
The Canadian-American Challenge Cup (Can-Am) was a short-lived racing series that enforced almost no rules, leaving the door wide open for innovation and pure madness. Its tenure from 1966-1987 spawned several groundbreaking cars driven by racing legends, including the Porsche 917/30.
The car was propelled by a turbocharged 5.4-liter flat 12 cylinder engine, producing more than 1,000 horsepower on a 1,765 curb weight. Mark Donohue raced the 917/30 to six consecutive race victories, nabbing the 1973 Can-Am championship.
7 1958 Porsche 356 A 1500 GS/GT Carrera Speedster - $2.5 Million
Of only 13 356 Speedsters made, Seinfeld owned the only Carrera Speedster in Aurantium Green, and its estimated value was $2.5 million, though it only sold for $1.5 million. This particular Carrera Speedster had an extremely rare sample of the four-cam 1.5-liter flat-four, which produced 110 horsepower.
Unfortunately, the company that bought Seinfeld's Speedster deemed it a fake and sought to sue the comedian, who then sued the dealership that sold him the car. Currently, the car's authenticity is yet to be determined.
6 2000 Porsche Carrera GT Prototype - $2.3 Million
Before the Carrera GT suffered from relentless infamy over its habit of catching fire or being an integral part of Paul Walker's death, it was the stuff of dreams. The GT was a Porsche supercar ushering in the new age.
With a roaring naturally aspirated 5.7-liter V10 producing 600 horsepower, the Carrera GT could hit 60 mph in 3.5 seconds and top out at 205 mph. The GT's engine was originally intended for the Footwork Arrows Formula 1 team and in Le Mans but was tabled until the Carrera GT was underway.
5 1990 Porsche 962C - $2 Million
Seinfeld was one of the two owners of this particular FIA World Sports-Prototype competitor before it was sold in 2016 for $1.6 million. It has a 3.0-liter flat-six with two turbochargers bringing its horsepower all the way up to 750. It has no livery, whereas the other 962C is covered in Repsol sponsorship.
The 1990 Porsche 962C shared little success with its predecessor the 962, which had a rich history in endurance racing having won Le Mans six times in a row. This is a piece of that racing history when Porsches dominated the race track.
4 1983 Porsche 959 - $2 Million
The first Porsche 959 was released to the public in 1987, but it began as a concept in 1981. Originally intended to race in Group B rally, the 959 used a twin-turbocharged 2.8-liter flat-six which somehow Porsche managed to squeeze 444 horsepower out of, despite its displacement.
It was mated to a five-speed manual transmission, plus an extra gear for off-roading. It was one of, if not the, most technologically advanced road car of its time, with computer-controlled suspension and four-wheel drive. As the fastest street-legal car in the world, the 959 topped out at 197 mph.
3 1986 Porsche 959 - $1.85 Million
What was released in 1986 was largely the Porsche from 1983 displayed at the Frankfurt Motor Show, with some aerodynamic modifications. Production didn't last long, as Porsche only made the 959 until 1988.
It was later discovered that Porsche had enough parts lying around to keep making them, and its original run of 292 was extended to 337 over the next five years. The 959's allure derives from its four-wheel-drive system, where drivers could select where the torque went. Its engine was primarily air-cooled but had water-cooled cylinder heads.
2 1970 Porsche 911S Henri - $1.3 Million
At first glance, the 1970 911S looks like any normal Porsche, but for the time it was a massive improvement from previous models. The 1970 911S came with a 2.2-liter flat-six engine delivering 180 horsepower to the rear wheels, and four-corner independent suspension.
This 911S was built with new USA legislation in mind which demanded greater safety than the Cabriolet had to offer, thus Porsche invented the Targa concept. Seinfeld's 911s is most likely named after "Henri Joffroy", a noted Porsche specialist.
1 1973 Porsche 911 Carrera RS - $1.2 Million
One of only 49 ever built, Seinfeld's 1973 911 Carrera RS uses a 2.7-liter air-cooled flat-six producing 210 horsepower. At just 2149 pounds that's plenty of power, and enough to reach 60 mph in a blistering 5.6 seconds, and top out at 150 mph.
This was by no means standard, as the non-RS 911s had smaller engines and weighed more. Also, the RS came with flared wheel arches with the intention of fitting larger tires. It's also the first appearance of the now famous Porsche "ducktail" rear spoiler.
