I personally don't rely on the police to find my stolen property. Police solve just 14% of stolen property cases. It's most probable the case ended up in a stack of low priority cases on some rookie's desk, and the vehicle was long gone out of local jurisdiction hours before it was noticed missing. I'd likely still want a police report, just for the record, but I don't have faith in them to find my property. Besides, I'd rather the police keep busy on higher priority cases.
All of my vehicles have a Tile hidden in them connected with an app in my phone. I can track their precise locations from anywhere, and get a notification every time one of them moves.
