I changed plugs on and tuned up an '84 Continental Mark once. I kept wishing I had additional elbows - on my arms - and said arms ended up looking like I had held them in a box of rabid cats for about twenty minutes. Changed plugs I never saw before they were out of the engine. And that's a car with a "normal" automotive engine compartment. So, everything has its challenges, but I do indeed take oughtsix's point about being able to at least endure all the torture in one place, without having to lurch back and forth from out- to inside to do it. And I love the discussion, thanks all.
