Wow, I'm amazed! The alarm was the first option that I selected. Sure, professional thieves probably won't be deterred, but I reckon if some hoon out there is looking for a joy ride they'd be deterred. I haven't got my XR6T yet, but a while back I had an alarm installed on my current car. I sleep a lot better at night now knowing that if anyone tries anything with my car (usually parked just outside my bedroom window) that it'll wake me up in a flash. And yes, if your car's stolen your insurance company gets to worry about it, but I bet your next premium would be quite a bit higher as the theft would be counted as a claim. Plus, if your car is stolen, you have to deal with the inconvenience, the anger and worst of all.... the wait for another XR6T! Do whatever can be done to prevent it getting stolen! (That's my line of thinking anyway.)
