I think nowadays the technology that is out there the newer the car the easier it can be taken especially them keyless entry cars and buttons on the door handles which you can literally picukp the signal of the key with a special device from the house if the car is in the driveway and drive of with it and deal with the tracker after if there is one from factory but even if a vehicle is put it in a container or a garage from metal all insulated with special foil that no signal can come through it can still be located and thats a fact
I assume that all luxury cars the likes bmw,merc,range rovers etc have trackers built in them, but i seen a documentical movie made in russia how they work with a smartphone with certain stuff on it and a obd lead and just bypass any obstacles in minutes and the car is gone in less than ten minutes with no smashed windows, alarms triggered etc..
For the likes of our cars they wouldn't even be interested in them as they are no value to them but there is other scum out there who would take it for parts or a joyride, simple stuff like an oldschool steering lock, alarms with secret button to engange ignition , aftermarket tracker with fuel cut off as soon as it leaves you'r desired area and sends panick alarm to your phone certainly can make it hard for the ****s to take your joy
