Bought another Mopar Today - Nitro R/T

[099 FEVER]

Bought a new Mopar it's my Wifes and we traded in my Yellow Scion XB. It's a Nitro R/T silver grey with the 4.0 V6. Has all the goodies except the security system. I don't like the one the dealer installs for cars on his lot and tries to pawn off on the customer for $500 bucks. All it is is a remote switch for a key chain to disable the starter relay in the fuse box. Real easy to bypass and doesn't fool the thieves. Does anyone have good experiance with an aftermarket security system that works similar to the Mopar Sentry Security on our trucks that seems to be very hard to bypass according to Chrysler. Will appreciate your comments, Thanks Murray.
