I have not seen this posted on any of the forums yet, so here goes.....
There is a website where you can log in to see what cars have been reported stolen in your area. You check the list and just keep your eyes peeled. Email updates are sent when new cars are reported in your area. If you think that you have spotted one of the cars, you call 911 to report it and the authorities take it from there.
If you have had a car stolen you can also log in to post details about it that will hopefully help someone spot it.
The website is at
https://www.stolencarreports.com/It is basically a neighborhood watch system for car owners everywhere. The more of you that sign up to help, the more cars that can make it back home to where they belong.
