ok, alarms, with alarms you get what you pay for, like darren said, there are a few car alarms out there at the moment. pricing start's for a standard car alarm at around the $199.00 dollar mark, you can pick up a car liner car alarm for around the $300 mark, they arnt to bad, dont have any presure switches, coded key or anything like that, just a standard alarm, imobiliser with out battery back up, me, personaly i have a very expensive alarm, it's a mongoose alarm, i realy cant complain anything about it, the, it has the following stuff in it
8x pressure switches on windows.
central locking dead lock, (like the new model comodores have, when you press the button and hold it, it will lock the central locking, making it impossible to open the door at all)
a proximity setting
and has several sensative switches around the body.
it's coded, and has 2 battery back up's,
all this is in my vn. (over kill i hear you say, well, im not taking any chances on my baby)
the pressure switches triger alarm if window is broken.
proximity setting will go of if people are to close (though this is a pain in the arse)
and the sensative swithces will triger alarm if someone try's to open or push or jack up the car. there is also the usual door triger's
2 battery back up's is because all someone has to do is pull 2 wires out of this alarm to completly disarm it, (it's like that with all alarms)
it cost me just under $1500.00 for it. i like this alarm, it's up to personal choice though, just remember, a car alarm wont stop yoru car being stolen, it's a visual deterant, a realy noisy one if that. if someone want's your car or contents bad enough, they will just take it
