A classmate of mine happened to mention once that for some early models of a particular Japanese car manufacturer (1980's I think) the engine would need to be removed in order to change the oil.
I was a professional auto mechanic in the late 80s, and I'd never even heard rumors of such a beast. I'm not going to pull the [citation needed] card, but I think this is one of those tales that got taller with the telling (Nissan 300Z's, for example, are a right PITA such that you'd briefly think that removing the engine would make it easier.)
There isn't an automotive engineer in the world that would keep their job after submitting such a design, let alone get it into production.
