Making a car difficult to steal

70 dollars. Not sure if anyone posted this. Briefly read it and the reviews. Appears to operate off text messaging or pager technology and gps. Has geo-fence feature as one of its activation features, will locate your vehicle and can remotely shut down your car too (probably has a relay, you can do what ever with it)
