Exactly. Toyota has even made parts for Land Rover before. I know on the LR3/4 they had all Denso engine electrical systems as well as several sub systems. I assume the new ones are the same. You can bypass a lot of systems on a modern Land Rover. The only things I can think of electrically that would completely disable a modern LR would be some kind of engine management issue. Every other system has a work around. Or you would have the same issue on another vehicle.Considering that the auto industry is worldwide with supplier networks in support of multiple manufacturers, there are few degrees of component level reliability differences. Now one vehicle may be more complex and use more components but that is product differentiation. Land Rover is no different.
