Jerry Seinfeld's 1952 Porsche is an America Roadster. Only 17 were built.  
My client and friend, the late Walter (Wally) Kieckhefer, raced this same car at the Pebble Beach road races and other venues back in the '50's.   In its last race, the America Roaster, driven by Wally was hit by Johnny Von Neumann in his Porsche 550 Spyder.  Wally limped the car home to finish 3rd in that, it's final race.  
In about 2007, I drove my 356C to a job owned by Wally.  He saw my car and asked if I was a Porsche enthusiast, to which i answered "Absolutely!"  He later showed me his scrapbook of cars he had owned and raced.  i was amazed at the early Porsches he had owned.  
A few of the photos showed this America Roadster, he called it his "Roadster".  He said he had crashed it and had sold it shortly after through an ad in Road & Track.  He lost track of the car after that.  
Through email and notices in the 356 Registry I was able to track down and verify that this car still existed.  It was located in Southern California and had been restored to a very high level by John Wilhoit.  The current and past owners had searched for the mysterious Pebble Beach driver but were never able to locate him.  I contacted the then-owner and got Wally and him together.  Wally still had the Pebble Beach "participant" plaque which he gave to the owner.
Sometime after that Jerry Seinfeld purchased the car from this owner.  
I was able to convince  Wally to attend the 2011 Porsche Race Car Classic (check it out on youtube and elsewhere) where he was reunited with his old "Roadster" and chatted with Mr. Seinfeld who brought this car AND the 550 Spyder that had crashed into him so many years ago.

The cars are the real celebrities and Jay knows it.

Classic cars like these are pretty much beautiful works of art

You see jay intrigued as a kid a smile as he approaches Jerry

Chick driving a vintage Alfa… super cool!

Farah's voice overides everything 🤣

Golden era of cars and coffee malibu

I swear,almost all years of Porsches look alike……..and so do their owners

It must be great for Jay, they’re have a meet and greet for a specific car so he just goes through his garages and pull one out! 🇨🇦

California is so beautiful.   The streets, the atmosphere, the mountains in the background, and beautiful weather.   Gosh, I've got to get out of Texas and live life in Cali.   Texas is a :face-fuchsia-poop-shape:hole.

If we all had that kind of money, we’d all have nice toys

My local cars and coffee looks nothing like this gathering!! Love all the cars, especially Jerry's very rare Porsche racer.

Those old Porsche are beautiful

Being a car guy, and in the automotive industry my entire life so far, I really am appreciative of owners who drive rare cars. Anyone can build them, not everyone can skip the trailer and drive them everywhere. That is, after all, the purpose of these works of art

Seinfeld knows his Porsche's!

What a beautiful machine…so happy to see Jerry enjoying it…!!!!

The paint on Jerry's is literally like a mirror.

Cruising is a lost activity due to excessive traffic and the obsession to get some place fast .
Cruising in a classic car IS the destination .

Smart guys back into a space & go out effortlessly / safely where they can see everything.

I like how they take time to park right in the middle of the space .No "I'm a big celebrity and my cars worth xx
