I am very interested in a Duramax but totally new to diesels. My question is for the diesel folks, does the GM discount really a discount when it comes to the diesels? I have noticed total sticker pricing of around 45k and the discount is about 36k. Seems this is not much off the sticker for such a discount. Also does anyone know if this includes all incentives such as rebates and so forth. Just trying to check on the best pricing and negotiating approach. I am excited about owning a diesel but do not want to get ripped off. One last question, is there a difference in the ride of the ext vs cc? I tend to like the ext better for looks.
