While we all get a chuckle out of Jerry Seinfeld’s Comedians in Cars Getting Coffee, it is no laughing matter when several of his extensive collection of Porsches hit the auction block. Extensive? Probably not the best choice to describe the estimated 47 Porsches that reside in Jerry’s $1.4 million custom garage in NYC. Hitting the auction floor in March will be three of his prized collection, including a 1974 911 Carrera 3.0 IROC RSR, a 1958 350 a GS/GT Carrera Speedster, and a extraordinarily rare 1955 550 Spyder. All in, the auction could fetch nearly $10 million. Take a look here.
