"I purchased this truck new in 2006. The entire family has loved it from the day we brought it home. Incredible power, great mileage, incredibly reliable and fun to drive. Could not have asked for a better truck. The 2006 LBZ Duramax Diesel is quite unique and sought after. Do some diligence on this truck. If in the market for a reliable, high-performing diesel...find a clean 2006 GMC Sierra 2500HD w/ an Allison transmission and the coveted "LBZ" Duramax Turbo Diesel. You won't regret it!"
