I thought there was a non-production Mustang or maybe a Corvette, built in the 60's, that required you remove the engine to change the spark plugs.
Maybe it was just an urban legend.
I got a lot of interesting conversation on the question is there a car that you have to Remove Engine to Change Spark Plugs? at cartalk.com.
I think the answer is nobody really knows. When the owner of one of these cars found out how hard it was to change the spark plugs they sold the car to some other sucker.
Actually there are quite a few answers. Sounds like a Monza, Porsche, maybe a vette, and some others had the "remove or at least disconnect and move" the engine to change the plugs.
