I always thought it would be cool to have a car with a rumble seat.

Cars with rumble seats are cool. I actually saw this car at a local establishment with the rumble seat flipped up. It's a Plymouth of some kind and its powered by a big-block Mopar.

It would be fun to ride in the rumble seat of one of these cars. Unless it was raining, or unless the car was involved in a roll-over accident. Then it would suck.
