I know you guys probably have a thread for this but I couldnt find it. I'm looking at purchasing a Cadillac between 2000-2004 but wanted to see what models are the more reliable/cost effective. For my job I had a 02 SLS for a few months and it had an issue with the security system that the dealer couldnt figure out. I'm cool with that same model or a Deville I'm thinking.
