El Camino Alarm system
I'm restoring and customizing my 1973 El Camino 454 SS.
It's starting to get noticed and it's getting me worried. I
already had one stolen from me before and hate to put all
this sweat and hard work into it for some snuck to just
take it. What Alarm system should I use? It's not garaged
so I need something that works other than a 9mm. LoL
any suggestions?
