Yea, I found it kind of strange that they were both so sure that they'd seen a lot of four door Suburbans from the 60's. For anybody who doesn't know: From the Suburban's first year of production, all the way up through that 60-66 body style, they were only made as two doors. The 67-72 body style introduced three doors, one on the driver side, and two on the passenger side. It was the 73-87 body style that the Suburban finally became a four door.
