Scott, What part of Mass are you from?
I got it in my IS300 (I live in Atlanta also) just because I have to park the car in a somewhat sketchy area, and I like the extra comfort that the Low Jack provides. As an added benefit, I got an insurance rate deduction when I told them I had Low Jack (not too much, I think $39 a year, but it definitely adds up if you plan on keeping the car for a while!) Back in the day, when my father bought his LS, he opted for big Low Jack package, with the special key fob and cell phone update, although he never uses the extra stuff. I think if you got the base Low Jack package you can have more confidence that your car will be protected and if you notify your insurance, it might pay for itself over the years. Plus, if your car is ever stolen, there is a much better chance you can get it back before something horrible happens to it (knock on wood)
I'll going through with this option, probably premium because I'd want to know as soon as it moves. There's lots of places in Atlanta that I'd want to keep an extra eye on it. Cheers !!!!
