Don't worry I'm careful enough when it comes to my car. Currently I have a wheel clamp, full disklok steering wheel clamp, de-locked boot, de-pinned doors, disconnected passenger handle and a mid-range alarm/immobiliser but before I get the screens in the alarm is being upgraded and connected to the central locking so that doors can be de-locked totally and security film fitted to the glass.
Besides that I'm quite known around my area and being 6'1" skin head with no neck is generally enough of a deterrent.
Thanks for your concern though mate.
