Ran into a corporate ex of Toyota who oversees the LC and he said their goal with this new generation is that it will be a vehicle that will have a 25 yr life span with repairs being made only by hand tools. They want this to truly go back to their roots and be a vehicle that is once again used in safaris, deserts and other areas where shops are not readily available.
Not sure how hard/ easy a hybrid engine is to work on but sounds encouraging.
