Car alarm

What type of car alarm do you or what would you suggest for 2 door convertible soft top?

This is what I think I want
1. zone sensor: in case someone reaches in.
2. impact sensor
3. proximity sensor: for the bad people standing there unzipping the windows.
4. siren: to wake the neighbors when cats jump on it. Just kidding I'll have this off when at home or set low.
5. pager: maybe I can call the cops or give a yell. hmmm or get shot I guess.

i would add a starter kill to that also

i would first buy a hard top or you are wasting money a pocket knife and less than a min the alarm can be disarmed
