Jerry Seinfeld’s most significant cars are not simply a list of expensive Porsches. They span Porsche competition history, early production milestones, rare variants and a one-off modern project—and Seinfeld has singled out one racing car as his most treasured possession. This is an editorial selection, not an official ranking or a claim that every car remains in his collection today: the clearest documented group is an 18-car consignment announced for a 2016 auction, while Porsche confirmed a later one-off delivery in 2023.
How this list is judged
Significance here means a combination of documented motorsport connection, place in Porsche history, rarity or one-off status, and Seinfeld’s own stated attachment. The 2016 Gooding & Company announcement provides a dated record of 18 cars consigned from his collection; it is not a current inventory. The 911 Classic Club Coupe, delivered in 2023, is a later documented addition. None of this establishes what Seinfeld owns today.
The cars below are ordered to foreground the collection’s competition identity, then its historic and personal landmarks. This is not a ranking by value. Gooding’s published figures are auction estimates from 2016, not sale prices or current valuations.
The 10 significant cars
1. 1973 Porsche 917/30 Can-Am Spyder
The 917/30 is the collection’s clearest competition-focused centerpiece: its Can-Am Spyder designation places it among Porsche’s purpose-built racing machines. Gooding included it in the 2016 consignment from Seinfeld’s collection. The available collection announcement verifies the model and connection, but does not provide an individual race record for this car, so its significance should not be inflated with unverified results.

2. 1955 Porsche 550 Spyder
The 550 Spyder is one of the three cars Gooding singled out as a collection highlight in its 2016 announcement. Gooding assigned it an estimate of $5,000,000–$6,000,000 for that auction; that dated estimate is not evidence of what the car sold for or what it is worth now. Its inclusion matters here for its place among the collection’s most prominently presented early Porsche sports cars.
3. 1959 Porsche 718 RSK
Gooding identified the 718 RSK as a collection highlight and included it in the 18-car consignment. It adds another distinct Porsche competition-era model to a group that ranges well beyond road-going 911s. The announcement does not detail this individual car’s race history.

- Convenient Envelope Included: White peel & seal envelope included for easy mailing and gifting.
4. 1958 Porsche 356 A 1500 GS/GT Carrera Speedster
This Carrera Speedster was another of Gooding’s featured highlights. Its 2016 auction estimate was $2,000,000–$2,500,000, a historical estimate rather than a current valuation. It also represents the collection’s connection to the 356 family and Porsche’s Carrera naming lineage.
5. 2000 Porsche Carrera GT Prototype
The word “Prototype” is the key distinction: Gooding’s consignment list identifies this as a Carrera GT prototype, not simply a production Carrera GT. That makes it a notable development-era entry in the collection. The published list does not give further engineering or development details about this specific car, so claims beyond its prototype designation would go beyond the evidence.

6. 1990 Porsche 962C
The 962C adds a later competition-oriented Porsche to the collection’s documented lineup. Gooding listed the model in its 2016 announcement, but the release does not describe this car’s individual race history. Its significance in this selection is therefore its documented model identity and contribution to the competition thread running through the collection.
7. 1974 Porsche 911 Carrera 3.0 IROC RSR
Gooding prominently featured this IROC RSR in the 2016 announcement. Its estimate for that auction was $1,200,000–$1,500,000; that is not a realized price or a present-day value. The model designation links the 911 to a competition-focused specification, making it an important counterpart to the collection’s dedicated racing cars.
8. 1963 Porsche 356 B 2000 GS Carrera 2 Coupe
This Carrera 2 Coupe appears in Gooding’s consignment list and represents another branch of the 356 Carrera lineage. Its significance is historical and connective: it shows the breadth of the collection’s early Porsche sports cars alongside the Speedster and the still-earlier 356/2.
9. 1949 Porsche 356/2, number 40
Porsche reported in 2015 that Ferry Porsche and his team built 52 Gmünd coupés, and identified Seinfeld’s car as number 40. In Porsche’s feature, Seinfeld described it as “Hand-built in Gmünd, everything’s original.” That statement conveys his attachment and the car’s character, while remaining his description rather than a separate authentication report. As an early car from the limited Gmünd-built series, it is one of the collection’s strongest links to Porsche’s beginnings.

10. Porsche 911 Classic Club Coupe
This one-off is the clearest later addition in the documented story. Porsche says Porsche Classic completed the Sonderwunsch project with the Porsche Club of America, based on a 1998 911 Carrera, and delivered it to Seinfeld in 2023. Its naturally aspirated 3.6-liter flat-six is rated at 381 horsepower by Porsche. Unlike most cars on this list, its significance rests on a documented one-of-one status and a specific, recent delivery rather than a decades-old competition identity.

A car that merits special mention even though it is not among the ten above is the 1970 Porsche 908/03, chassis 008. In a 2018 Porsche interview, Seinfeld called it “The 1970 Targa Florio-winning Porsche 908/03 chassis number 008” and described it as his most treasured possession. That is unusually direct evidence of personal significance, but it is a statement from 2018, not confirmation of current ownership. In the same interview, asked for desert-island choices, he named “A 356 Speedster, a 964 Carrera RS, and a 918 Spyder.”
What the auction estimates do—and do not—tell you
| Car | Published estimate | Source and date |
|---|---|---|
| 1955 Porsche 550 Spyder | $5,000,000–$6,000,000 | Gooding & Company, 2016 |
| 1958 Porsche 356 A 1500 GS/GT Carrera Speedster | $2,000,000–$2,500,000 | Gooding & Company, 2016 |
| 1974 Porsche 911 Carrera 3.0 IROC RSR | $1,200,000–$1,500,000 | Gooding & Company, 2016 |
These are estimates published for a 2016 auction, not confirmed hammer prices, appraisals, or current market values. They help explain how the cars were positioned for that sale, but they cannot support a present-day ranking by value.
