Well hello folks, wayne here. I am a long time GM man, but never owned a diesel...YET. I have been lurking on the boards for awhile trying to see why some many people have complaints about duramax. Well, with my reading and my recent test drives, I'm almost sold. My final information mission is to inquire about lengevity issues. When I buy a vehicle, especially a $45K one, it had better run 300K with little or no problems in my book. Of course regular maintenance is of the utmost importance, but you know what I mean. If anyone has any links to threads or posts about longevity with regard to the duramax, I am all ears....or eyes actually. Thanks and I sure am glad to have found this vault of knowledge.
