"BMWs are hard to steal so you don't need an alarm"
Surely BMWs are desirable, therefore likely to get stolen? However 'hard' car makers might think their cars are to steal, they are wrong. Any (most) unprotected cars can be taken in under 2 minutes.
Save the money and fit an aftermarket alarm. You'll get something much better.
