The mystery project Jerry Seinfeld hinted at via Twitter is a star-studded new reality show tentatively titled "Comics and Cars," The Daily's official blog revealed.

Details are under lock and key, but Flash Daily was told the show will feature Seinfeld, a classic car enthusiast with a penchant for Porsches, and comedian pals including Alec Baldwin, Ricky Gervais and Larry David test-driving cars from their past, trading old memories and cracking a few jokes along the way.

Seinfeld and Gervais recently were spotted taking a 1960s Austin-Healey for a spin after renting the vintage car from a dealership in New York's The Hamptons for $1,000 per day -- a bargain considering Seinfeld's fortune.
