Not the only "pain in the ass" car maintenance wise. It's my understanding that the new Porsche (991) 911 has to have the rear bumper removed to change the air filters. IMO, that will always be costly for such a simple item. It's also a slight deterrent and/or turn off to acquiring a truly marvelous vehicle.
