Apart from having a siren go off if anybody opens a door etc is there any real point in having an alarm on modern cars???
Apart from the alerting feature the anti theft side of having an alarm is taken care of by the factory.
The built in factory security is basically that without the correct key it is for all practical purposes impossible to start as the ECU will not allow, ignition, fuel or starter to operate.
The most important thing is preventing the car being stolen.
Apart from you responding to the siren, no one else will really pay attention to it or respond to it.
I had a high end alarm with anti jacking feature in my 1996 Mitsu Eclipse Turbo in the USA as they didn't have mandatory immobilizers in those days. 
I didnt know the RA and EVO have a factory siren etc????
Mathew I think alarms are good if you park your car on the street at night. How often do you here all the cars in a street have been broken in to. It only takes one alarm to go off and the thieves take off. 
Often your insurance premiums will be cheaper as well.
My question is how long do new alarm last for? My experience with alarms they only lasted about 10 years.
