Renowned comedian and avid Porsche collector Jerry Seinfeld has been sued for selling an alleged “fake” 1958 Porsche for $1.54 million.

The company that bought the car from Seinfeld, Fica Frio Limited, filed a lawsuit in a Manhattan federal court last Friday seeking unspecified punitive damages. According to the suit, the firm said it paid $1.54 million for the car at a March 2016 auction in Florida. Later on, the company said it learned the car was not authentic.

To add insult to injury, the buyer says Jerry Seinfeld intentionally misrepresented the authenticity of the whip. Apparently, the person who sold it to the comedian wrote in the history file of the Porsche that they didn’t have a lot of information on the car. The previous owner purchased it from a broker “who would not take me to the car’s original location to meet the family that owned it originally.”

Concerned by the findings, Fica Frio took the car to a leading historic Porsche dealer which investigated the car and found it wasn’t the real deal. Fica Frio also claims the comedian and Porsche collector apologized by voicemail last June and promised a refund. However, that never happened — according to the plaintiff.

Jerry Seinfeld’s lawyer says the lawsuit is “frivolous”

As for the defendant, he completely denies the accusations. Seinfeld’s lawyer, Orin Snyder, described the suit as “frivolous” to TMZ. “Jerry has been working in good faith to get to the bottom of this matter. He has asked Fica Frio for evidence to substantiate the allegations. Fica Frio ignored Jerry and instead filed this frivolous lawsuit,” the lawyer said.

The car in question is a 1958 Porsche 356A 1500 GS/GT Carrera Speedster, one of approximately 56 cars built with alloy panels. Sold at a Gooding & Company auction in March 2016 for $1.54 million, the car is believed to be the only example originally finished in Auratium Green.

In the listing on the auction house’s website, the classic Porsche is said to have undergone an “award-winning restoration completed by European Collectibles.” The car was sold complete with a Porsche Certificate of Authenticity (this will get interesting if Fica Frio’s allegations prove correct), Kardex, tool roll, and handbooks.

Featuring coachwork from Reutter, the 1958 Porsche 356A 1500 GS/GT Carrera Speedster packs a 110hp 1.5-liter flat four-cylinder engine fitted with two Solex 40 PJJ-4 carburetors linked to a four-speed manual transaxle.
