One of my friends got his 08 LMM last March or April, a Sierra. When I got my Silverado a month ago and we met up last weekend, he was jealous. He loves the hood vents and Duramax/Allison badges. I hadn`t even paid enough attention to the newest series enough to realize the Sierra`s didn`t have them. Well, he`ll only have to live with that for a couple more years....after 10 months he`s already put over 100K on his, and figures he`ll roll it out at around 350K or so.
