Years ago trackers were about £200 a go and more, it wasn't until my daughters car was stolen (and burnt out) that I thought of looking into them and was surprised at how inexpensive they were now. Like you my house is covered by cameras, unfortunately they're no good when the car is in Manchester or anywhere else than outside my house. Regarding confidence, I am a lot happier knowing where my car is simply by going online and looking at the display on the website, and also that can disable the car should need to. If a thief wants to drive MY car at 130 MPH I don't mind cutting the engine on him, although it can be done so it only cuts the engine when going under 12 MPH. Do a search on Amazon (other sites are available) and it will show you alternative sellers who do have them in stock. I have the 'B' version which has a remote fob, but that doesn't really do much (I just like gadgets). Here is part of the display of my car being moved from the secure parking to the Airport and some of my journey home after returning from Spain last month, each of the dots indicates date/time.
