Hi Stefan,
Have you driven a TRD Pro? For a "truck" it's pretty posh. I'm actually pretty uncomfortable driving luxurious cars, so I had to get over that when I bought mine. Of course, to me heated seats is luxury.The suspension is unreal on washboard roads, and it still rides pretty well on the highway.
I'm sure you can't go wrong with any of the three models you are looking at.
Leather Heated seats are 90's luxury. The TRD Toyota is about as base trim as it gets when it comes to interior, even the 4runner 'Limited' is still a Toyota on the inside. The Grand Cherokee and the LR4 are on a whole other level for comfort, gadgets, and features.
