The three models you mentioned are all hard-core off-road vehicles with non-load-bearing bodies. The minimum ground clearance of lexus LX570 and domestic Land Cruiser 4.6L VX-R is 225mm, and that of England and finidi qx56 is 243mm.

However, off-road ability can not be reflected only by ground clearance. Personally, I think these two Toyota cars have strong off-road ability. There is no problem for three cars to enter Tibet

They are all top SUVs, and the performance is not much different, depending on personal preferences.

Not bad money is QX, LX570. Lexus should have lifetime free maintenance.
