Just turned 900 miles on my CTS and when the car was delivered there was a smudge across the glass for the DIC. It will not come off. It needs to be replaced. I'm wondering will they give me any problems under warranty. I didn't create the smudge. Also I won't be taking it to the dealer I purchased from which is about 40 miles away do you think my local dealer will treat me fairly on warranty work? Forgive me guys but I'm use to Chevy service on my 04 Vette which is horrible. This is my first Caddy purchase.
