Ok, I know many owners are attached to their Land Rovers and put a lot of effort (myself included) into making it a little more personal. I would be pretty upset if some low life took my vehicle, and to that end I have various security measures on my property to prevent such an event. But when I'm 'out and about' (when its most likely to be targeted) I have to depend on the vehicles security system. How secure that vehicles security system is depends not only on the vehicles 'built in' system, but also upon the ingenuity of the owner fitting further security ie; battery isolator, fuel cut off etc. But if ultimately the thief overcomes these deterents, it all comes down to having the vehicle properly insured.
