I have already such a tracker in my car that connects to the OBD2 and has its own 3G or 4G chip. I have an app and can track where my car is and could do some stats. Why did I get it for free? It was a joint deal between the insurance and the car garage and they probably can see where I drive - the garage wanted me to do all maintenance in their garage and the sensor/app company offered me to be my car insurance. So also the dealer or garage will be interested to know where you do your car maintenance. All in all I should probably take it out but I see a little benefit and do not care about that amount of data that I share (any cellphone manufacturer will have a million more data points).
