Far from more fragile.The problem is even though we are taking about Toyota Land Cruiser I still believe 200 is much more fragile , less capable and a lot more complex than the 100 and as numbers go up it gets worse,
I may be wrong, but history proved that’s true with every automaker.
Hummers, H1 H2 h3
Toyota’s, 60 80 100 200
land rovers d1 d2 d3
Tacoma gen 1 2 3 4
Numbers go up capability drops, complexity goes up.
100 series is what I would consider sweet spot.
