I regularly take adults in the back. Its actually very spacious and comfortable back there even for adults. Id say 5ft 11 is the max you could fit comfortably. Two kids should have absolutely no problem as i also regularly take my 16 year old sister in the back as well. Only person that doesnt fit back there is my 6 ft 4, 250 pound brother. The dude is a monster, he could drive from the backseat with the front seat removed.Strongly considering picking up an N. I have an 8 and 6 year old. Anyone have experience getting kids of this age in and out on a regular basis? Thanks
