Welcome to the forum! I hope that you have reasons to stick around other than this one question, but if not then you should leave a satisfied guy! The rumble seat was an option. The buyer either had a trunk, or he had a rumble seat. With the rumble seat the storage space was limited to the foot space in front of the seat, plus some space atop the seat bottom, but only what would fit as the rumble closed and the seat back pivoted forward. If the rumble seat was open then something larger could be toted around, but it would be exposed to the weather, and also clearly visible/available to anyone walking by if the car were parked and left unattended. One person and a guitar case would fit easy, two people and a guitar case would be tight, but would probably work with the neck upright between the two passengers. Make sense?
