I wouldn’t have pegged Jerry Seinfeld as a car guy. But as this clip of Jay Leno pre-interviewing the scheduled first guest onhis fall NBC show reveals, I was wrong. Leno refers to him as “one of the foremost Porsche collectors in the world.” His garage includes Steve McQueen’s 917 from the movie Le Mans, and a 908 that won the Targa Florio in 1970. If the car talk scares you, just fast-forward to 1:00, when they start chatting about the insanity of people lining the streets for that open road race.

Leno: They finally did away with those kind of races because, I don’t know, too many people were killed and injured.

Seinfeld: I know, but…what’s the downside?
