Reminds me of the vehicle from the 70's where you had to tilt the engine up to remove one of the sparkplugs. This was back when tune-ups were a common preventative maintainence. A typical case of the design engineers not getting the maintenance folks involved earlier enough. No one asked "Hey, guys, if we build it like this, can you fix it when it breaks?"
It took some backyard mechanic to figure out that if you drilled a large hole in the wheel well, you could get to the spark plug, Mechanics would use a hole saw, then install a sheet metal plug to seal the access hole.
