I don't think so. In my time, I've noticed Toyota and Ford being the worst offenders when it comes to engineering things so they are difficult to do yourself.
It's not a military secret that manufacturers would rather you ended up with their dealers than somewhere else. Why? Their dealers sell their parts. Other places don't.
The oil in our GS350 is kind of a pain to do itself. Why they mounted the oil filter down low, horizontal, in front of the engine? I have no idea. But at least they made a trap door in the undershield so I can get in there without having to take the whole thing down to reach the dumb thing.
