the mysterious silver car

I could swear there are many different people using this silver vehicle .  This is the vehicle that comes to clean the church  about 2:30 a.m. every morning  however about a week ago there was somebody else using the vacuum but it was the same silver car .  This is also the silver car that I've seen sitting across from Starbucks  while I was there . This is also the silver car that had  one of The Bobbsey Twins driving it
