I think people are slightly missing the point in all this.
Even if you disable the keyless entry or use the faraday box, if they gain entry to your car from a broken window then it is very easy to clone a key once inside. Yes I know if someone wants to steal your car they can get it lifted etc blah blah all that but the likelyhood of that is very very rare where as Key cloning or keyless method is increasingly popular and very easy. Having the ghost is very discrete and would require the car to lifted away, again which is very rare, I doubt criminals would do that for 30k motability car.
The reason I mentioned the ghost was for people who maybe spent alot on their AP (5k believe it or not ive seen people spend on extras etc) and want it to be safe incase stollen or maybe wanting to buy the vehicle afterl
I was thinking of getting this for my own personal vehicle and also mentioned how I was unsure if motability would even allow it in the first place.
