hey i have a 2005 Cadillac STS V8 and it doesn't ride too smooth i took to it the dealership and they changed one shock but its kinda loud going over bumps and it doesn't feel too smooth anyone know that it could be........oh yea and it shakes a little bit on the high way and my warranty is up...
So i just bought a 2005 Cadillac STS v8 and it doesn't have the navi? So i was wondering how much would it be for me to go to the Cadillac dealer ship and have them put in the navigation system and the seats with the speakers in them??
