But, this issue affects pretty much all premium cars. Im sure there are much more accessible targets including the RR Sport which suffers from the same Canbus thefts accessed through the rear hatch. BMW X5's, Audis and Mercedes also are targeted.
I dont think there's any real way of getting around it apart from keeping your car as secure as you can.... apart from driving something which isnt as desirable I suppose.
The other thing is - are they actually canbus thefts or keyless thefts? The pouches are rubbish and stop working after a few months yet people seem to think they last forever.
I dont think Canbus thefts work with the Ghost immobiliser so I think that would definitely be a sound investment
