"Bought in 2003 when Ford was supposedly the one to buy. Glad I went with the Duramax. Runs smoothly and much quieter than Dodge or Ford. Getting 17 to 19 mpg empty. 13 to 15 mpg with a 3300 lb truck camper on it. Runs up the hills past all others. Most comfortable vehicle I have owned. Had some initial computer problems which were solved and never resurfaced. Only bad point thus far was rear brakes had to be replaced at 40,000 miles. I expect this truck to be on the road for a long time."
"The GMC Sierra is meat and potatoes. IF you are looking for a dependable truck, there are few that can match the Sierra. Can't say the gas mileage is impressive by any stretch. Some advice: have a car for long trips."
"I have owned several brand new GMC trucks over the years, most all purchased from the same dealer, and the same salesman. When GM built the truck we have now they sure did it right. We have a 2006 GMC Sierra 1500 Hybrid Ext. Cab SLE, 4x4, leather, this truck is fully loaded to the MAX!! This truck even has 4 110v. outlets on it, that sure would be handy if your power was out, or at a construction site. This truck stickered for $42k new. I traded in my 1999 Chevy Silverado 2500 Ext. cab 4x4 with a 150k miles on it. Since buying this Hybrid we have not yet checked the mpg, but I can sure tell you that it does get real good mileage. On the hybrid trucks they come from GM with a 8 year 100k mile warranty on all the hybrid parts including the batteries. This truck has the best warranty I have ever seen. We plan on keeping this truck for a long long time. In my opinion this was one of GM's best looking, and best performing trucks they ever built. I have owned several GMC trucks over the years and don't recall ever having trouble with any of them. I would highly recommend GM trucks to everyone, especially if you want an extremely reliable and durable long lasting truck."
"Waited for GMC to come out with a 1500 crew cab, big mistake this truck is not worth the money. Steering column rattles, electrical problems with 4x4 switches, front axle seals leak, drive shaft clunking, air conditioner failure, 15 mpg, radio losses mem., door lock failure prohibited entry to vehical and these are just the major problems. Will not be buying GM again."
"Smoothest shifting transmission I've ever owned. Roomy and comfortable. Plenty of passing and towing power. All of the amenities of a Cadillac DeVille, just a lot more rugged and versatile. Rides extremely smooth for a 4x4. I plan on keeping my 2002 for a long time."
