Best Alarm for Boxster 987
I have a 987 Boxster and I would like to upgrade the alarm to something that can detect say someone trying to deface the car or get in through the soft top etc. My brother has had someone take his symbol and deliberately damage his car on two separate occasions and I don't what my car to suffer the same fate.

Any suggestions?

I was looking at the Viper. Is it any good or can someone suggest something better?

THANKS
ANDREW
