any name brand alarm like viper ,clifford are good but it's more about the add on stuff that makes it more secure such as pre entry detection ,battery backup,battery backup siren ,hood deadlock,starter & ignition kill ,fuel cutoff . It also depesnds how well the installer hides the stuff I would have a independent shop that does custom work do the install . unless you plan on doing it yourself ,just stay away from chain stores they just slam your alarm up in your dash .
