Consider the 10 seat option - you get the driver & passenger up front, 2 2-seat units, 1 1-seat unit and in the rear a 3-seat unit. I removed the 3-seat and one of the 2-seat units. This lets you have lots of options - and have a walk through all the way. Only the rear seat comes with release handles, however all of the seats can easily be removed - you just have to fashion something to catch the release catch - I used a nylon cable tie.
