I really like the Intelliguard series, especially with the anti-carjacking and coded valet. With the new supreme court ruling that you're responsible if someone steals your car because you left the keys in the car, it's reassuring to know that if someone just jumps in my car, it will turn itself off down the block. I was debating between the Viper 790xv or the Intelliguard 7000 and went with the Intelliguard because it has more features and is made by Clifford. I also like how you can directly wire it up to honk both the stock horn and Clifford siren, as well as built-in turbo timer. The new Viper 791xv and Clifford Matrix RSX3.5 have the built-in turbo timer (if only I had waited). I guess in summary, I would say go with Clifford Intelliguard or the Matrix RSX3.5 since I believe the matrix uses more clifford sensors/parts.
