I just bought a used 2005 Suzuki Verona with a fairly new car alarm already installed. Before I bought the car I did some research on the alarm since the last thing I wanted was some sensitive alarm that goes off every 2 minutes. Eventually I bought the car and I am so happy that I did! The alarm is great and I luv the little LCD remote that comes with it. I am so releived I found a car with an alarm in it so i don't have to go and find one myself! But for those of you who aren't so lucky, check out this alarm:
