I got a new Apple iTag cost $30 dollars about the size of a of a quarter. It works with the Find My I Phone app and can be tracked supposedly all over the world till the replaceable battery die, Apple says about a year. I’m going to hide one in my Elise so if takin I’ll be able to find it (show the cops where it is. What do you think? Whenever someone else (dealership, repair person, etc.) drives your car you can track it.
