I'm not sure specifically about near where Mercedes are made. But there are many haunted house stories all over the world. For example, in some old European towns, there are houses with a long history where people have reported seeing ghosts. Maybe in Germany, where Mercedes is from, there could be some old buildings with spooky tales, but I haven't heard of any directly related to Mercedes factories.
There may or may not be haunted houses near Mercedes - making areas. However, generally, old buildings are more likely to have such stories. If there are old, dilapidated houses near the factories, they could potentially have a spooky past. But it's hard to say for sure without proper research. One type of story that could be there is about a house where workers used to live a long time ago and something tragic happened, leading to hauntings.
