My dad has been an antique (primarily 1920's and earlier, authentic) car geek for a long time, and he and my mom bumped into Jay Leno at a car meet years ago.

While there, he was just one of the guys, just there for the cars, and he definitely knows his stuff.

I think of him as a car guy who got a job as a late-night host so that he could pay for his true love.
