A paging system "sounds" good. But lets face it, unless you have the car in the driveway where a standard alarm would be heard, you would probably only return to your car to find it gone or damaged. You gotta ask yourself "How fast can I run 300m, 600m, 1000m" If you really want to do something hi-tech, go for the satnav/tracking system that will tell you where your car is and/or going to. IMO - Just a gimmick but different stroles for different folks After all how many XR6T's are gonna get stolen....they aren't exactly the rarest cars about so they dont fit the profile for organised crime and joy riders will usually be deterred by an alarm and the imobiliser system. It's more likely that a window will be smashed to steal your cars contents. Oh I almost forgot to mention, I got the standard Ford fitted system.
