Kerry; Rather then putting in the typical jump seats in this car why not do a variation on the Lehmann-Peterson conference arrangement that they built into Lincoln limos? Basically what they had was a pair of rear facing seats on either side of a center console which could contain a bar, or a T.V set or both. The difference that I would suggest is to arrange them so that they flip up, much like the rear seats in some pickups, and fold away into the back of the divider. Between the two seats you could build a flip down table, much like an English car has with possibly some decantors and glasses stored in the compartment inside. From perusing pictures of several old limos, and eight passenger sedans, the jump seat frames/mechanisms look rather complicated to duplicate, unless you can find some from a junker sedan. All that the flip down seats would need is a decent wood frame and a strong pair of knife hinges. The seat backs could be built into the divider and be fixed. I wish that I could draw you a diagram of what I mean because a picture would say a thousand words. To get an idea just think of the bottom of the divider as a shallow cabinet in a camper, only more refined and more nicely finished.
