i need to get some security myself, currently locked up in an enclosed compound though.
A pedal box and steering wheel box is a good plan. There have been posts on here about people cutting straight through pedal claws though, it just makes the job harder and less appearling. however as it is it's normally defenders that are stolen as opposed to series vehicles. That said, series landys are going up in value. Where are you parking yours? My concern is that once i have mine home it's on the road, so i am getting a clutch claw, a wheel lock and i already have an electrical immobiliser. They're cheap and easy to fit, though not exactly high security, will stop opportunnists but regardless of security, no matter what you do if somebody really wants it, they'll have it.
