the g wagon is base on the strada n with leaf springs although the montero sport is very related to the g wagon since the montero sport use to have leaf springs also but was modified to have coil springs for better rider comfort.

in my opinion, toyota 1st, new design, new engine...can't go wrong with a toyota.

2nd mitsu bec. 4m40 engine(same as a gen2.5 paj so abundance of parts in the next 10 years, same under pinnings as the strada n pajero so u aldso can't go wrong with this choice.
