I wouldnt bother with all that fancy stuff, I hope when you bought the car you have recipts for the following otherwise you might be in for some pretty hefty repairs with the milage you have on the car. 1. pnp switch about 500 bucks, when it goes bad the car starts in 3rd gear, 2. evaporator coil about 1200 bucks when this goes a/c leaks freon and a/c wont work. 3. abs modual about 700 bucks, when this is bad and they do go bad your abs trac lights will ficker on and off and you wont have abs. also all the little things that cost ya, these cars seem to eat brake pads, I had to replace all my rotars calipers and brake pads, and no I dont have a heavy foot I drive like a girl, because I am one. dont get me wrong I love my car but it is nickleing and diming me to death. I have 149,000 on mine its a 96 glt. good luck with it. kelly
