The Autowatch Ghost is a stunning product that is installed in a hidden place in the vehicle on the car’s computer network.  It stops the car starting until certain (owner selectable) buttons (such as electric windows switches, or steering wheel buttons) have been pressed in a certain order.
Autowatch Ghost has recently gained TASSA security approval and now requires it’s installers to be TASSA approved and DBS checked to ensure it’s security devices are only installed by trustworthy people.
Autowatch Ghost costs £449 installed.
