We currently have a minivan and are considering an R-class in a couple years when the minivan is used up. But an ML with third row seat might be an option, depending.

Honestly, how practical is the third-row seat? Can 2 adults fit back there for any length of time? With the third row seat installed, is there any cargo room left? Can the seats be removed easily? Also, this might sound crude, but can a sheet of 4 x 8 drywall or plywood fit in the ML?
