Jaguars are one example. Certain models of Porsche have dual oil
filters - and one of them can be changed only after removing a fender.
And I know I've seen a car where replacing the spark plugs requires the
engine to be pulled.

Of course with airplanes it's worse. Ever try to change out a prop
governor on an M20-F Mooney without pulling the engine off the mounts?
I don't believe it can be done.
