We need to rent a 4x4 next March to travel from San Jose to Dominical. I'm confused about which makes and models are the roomiest, since some of the vehicles are older models, or are a little different than the models in the states. Do the vehicles that accommodate 7 passengers have much room in them? Will passengers 6 & 7 be sitting backwards, or sitting with their knees up by their noses - lol? Does anyone have any experience renting a large vehicle that can advise as to exactly which type we should get?
