A good way to protect your car as best as possible is to follow these simple steps:
1. Don't advertise your car by posting on facebook, instagram etc - to let everyone know you own the car along with posting pics of where you actually live. That'll give thieves an idea where to look
2. Don't post info about your upcoming trips, vacations etc - because you'll let everyone know if you're not at home, and the car may be a sitting duck, waiting to be stolen.
3. Keyless entry/start - keep the keys in a lead box away, AWAY from the car. Not in the hall by the front doors.
4. Have cameras looking at the car
5. Put the car in a garage if possible
6. Have a sort of mechanical deterrent such as a Disklok (covers the whole steering wheel, not that simple to remove), or a pedal lock (locks all pedals together), or a transmission immobilizer (old school Mul-T-Lock which locks the gearshift).
7. Install a kill switch. A simple hidden switch to disable the fuel pump, or ignition is a great stealth device to prolong the time to steal a vehicle
8. Have a GPS tracker on the car. Sure, it will not help if a car is stolen and hidden underground, but you will have some idea of where it is, or where it may be. Much better than nothing.
