I am in the market for a quality security system before I even begin to transfer all the audio gear from my last vehicle(technically my dad's now). Does anyone have suggestions on systems that are both cheap and upgradable. All I am looking for now is the basic keyless entry system that disables the starter and makes some noise.
I am thinking Viper but need to know if there are other, cheaper alternatives. The ability to upgrade is the strongest selling point for me at this point.
