I got the viper 2way system installed in mine. ignition cuts off if you press the brakes without the key inserted and in the ON position, or if the hood is opened. Plus the transponder has a 1/4 mile range. I'm happy with it. But it was 500 installed... so yeah, not cheap, and I watched the guy do the install.... DEFINATELY not for a DIY job if you don't know precisely what you are doing.
