tracker ONLY will not be a good idea as cars with trackers can easily be snatched and professional mafias can easily disable it. also, the tempering of wiring is another issue for newer cars. people opt for tracker only to track their fleet of vehicles, driver's location, Uber/Careem car owners. only comprehensive insurance saves an asset for all sort of damages/thefts/snatchings for a total peace of mind. this is my experience based on ample time spent in the insurance industry.
