I like the alarm because it includes the glass breaker sensor, which is nice especially if you have a radar in the car. I'm going on my 1st year of ownership without the alarm and to tell you the truth I don't think it's a big deal. I rather spend the $$$ on something else like the CF spoiler or the mirrors.
