Re: Which vans have seats that fold into the floor? Going back to the OP--we have a 2005 Nissan Quest, and the 2nd row captain's chairs fold down almost flat. They don't go into the floor, but the floor of the 3rd row is slightly raised, so the 2nd row seats collapse to create an almost flat floor. We've only used it that way a few times.
Folding tops and side curtains for rumble seats were available for some cars (including the Ford Model A) but never achieved much popularity. Among the last American-built cars with a rumble seat were the 1938 Chevrolet, the 1939 Ford and 1939 Dodge and Plymouth. The last British built car with a dickey seat was the Triumph 2000 Roadster made until 1949.
