Your right about the LR3 being boxy too, my wife didn't want one for that reason, but as boxy goes I think it's got some nice lines. Not sure about difference in cost in the states but over here the LR3 is significantly cheaper than the RR, it's also thought of as more offroadable,there's a whole range of bolt on bits. However I must say, for what you want it for, if you have the money and don't mind high running costs and also scratching your colour coded fenders the RR HSE takes a lot of beating. The Grand Cherokee is an obvious contender but has no where near the same amount of room inside or level of refinment, that being said you could probably buy 2 for the same price as the RR HSE
