To all these fools who think an alarm is the answer, wake up.
One of my friends who is an auto-electrician broke into my car cleanly and then started it regardless of the alarm and immobliser while I was standing there, took him about 40 seconds and no alarm was triggered.
Get yourselves a GPS track and good insurance because at the end of the day, if a professional car thief wants your car, they will get it. So stop giving people a hard time for not having an alarm when they've just gone and lost their pride and joy, I doubt very much if they posted it on here in order to get flamed by you keyboard warriors. Put yourself in their shoes and don't pay them out FFS
