In my experience, these vehicles have convenient non-moving engine parts (grounds):

1989 Jeep Cherokee
2002 Ford Escape
2000 Honda Civic
2000 Mitsubishi Galant
Various Mercedes sedans

It would be nice if the part was neon orange, but still the part has not been that hard to find. By the way, the reason for not connecting to the negative dead battery is because you risk igniting hydrogen gas from the battery. I have never heard of this happening, but if it happened only once in history, that's enough.
