Vettegirl,
I have a remote starter and additional alarm on my SSR. The alarm does give me the added protection because both alarms have to be disabled if someone is trying to take the vehicle. The alarm has a motion sensor which will also trigger the alarm if the car is hit or the window broken, etc. The alarm will also send you a signal if this happen. So if you are in your home, office, etc the alarm will signal you with a display of the activity. In other words, if your car is being hit the alarm with chirp /vibrate and have a symbol that shows the car being hit or broken into. The alarm is good for about (35) feet or more. I have never tested it's limits but I have been able to disarm my car from a block away. Also this alarm can be programed to pop the trunk. This alarm also is the first alarm to offer a color screen. All of it's signals/alerts are in color. Now, if you get the alarm that I have which has the remote start feature, you can program the vehicle to start while you are inside your house, office, etc. I have activited both the alarm and the starter from about a block away. The remote start feature also disables the engine if someone gets into your car and trys to operate it without the key. The key must be in the car before you can drive away. Specifically, after starting your car with the remote starter, as soon as you get into the car you insert the key in the ignition and turn it to the "On" position. Do not "Crank" the car. Just turn the key to "On". You can then shift out of park and drive away.
It is great! Now if you also get the alarm and remote starter that I have the alarm also has the ability to be programmed to lower the convertable top remotely. I am scheduled to have mine programmed to do that next Tuesday. You will also need some additional minor equipment (inexpensive-so I'm told) to do this.
Good luck. Protect you baby!
