I wouldn't vent to much at car manufacturers. They obviously do the best they can, with the technology available at the time. But, a thief is still a thief. Maybe vent more at the Courts for the pathetic sentences given to car thives, or the lack of interest police forces have in following up car thefts. And £100k cars get nicked like this as well, all the time.
My choice about theft actually was referring to having a tracker fitted to my car or not. As someone else said on this very forum, what would you like? Your car back which may have been ruined by some oily snot driving it like the clappers for days before it was recovered, when Tracker managed to locate it, or the cost of Gap Insurance?
So, I went for Gap Insurance.
GAP insurance is just yet another insurance product which is just another gamble. If you don't need to claim, what a waste of money. If you need to claim then it's the bargain of the century.
Personally I don't take it but there is no right or wrong answer just a right or wrong outcome and to know that you will need hindsight
