Faults:

Leak in gas tank 1 week after purchase.

Driver's side door hinges seized up.

Interior door trim not secure to the body.

Front axle boot torn.

All above items were overlooked by the used car dealer I purchased it from.

General Comments:

Nice truck overall in SLT trim.

A lot of options.

Still getting used to size since stepping up from a car.

Should have gone just with the 5.3 motor, since I don't really tow anything. Just wanted the 367 horses in the 6.0.

Faults:

Absolutely nothing.

I bought this truck new off the lot in Sep/07, and have since put 70,000 kilometers on it. It has been rock solid reliable throughout that time, with not a single trip to the dealership required (I do my own maintenance).

I purchased it to haul a truck camper in the bed, with my boat hooked up to the hitch. It performs the task flawlessly. There is always power to spare, and the Allison 6spd automatic transmission is superb.

I'm a tall guy (6'4"), and this is the most comfortable vehicle I've ever owned. There is plenty of leg and head room available, without even requiring the seat to be pushed all the way back.

Originally, I wanted a Ford Super-Duty because I like the styling better. The GMC/Chev line was (in my opinion) the ugliest of the big three, but I decide to go with it anyway because of the reliability problems with Ford's 6.4 diesel, and Dodge's automatic transmission. And now I'm very glad I made that choice.

I can't say enough good things about this vehicle. I'd buy one again in a heartbeat.

Faults:

Nothing.

I have the Sierra Classic 1500 Extended Cab Z-71 4x4; 2007 being the last year for this body style.

This truck handles like a car and rides like a Cadillac. The interior of the extended cab has the comforts of a luxury car; I will probably never own another car simply for the lack of need thanks to the versatility of this truck.

The engine is very quiet and more than powerful enough; the flex fuel capability allows me to use the E85 Gas. E85 Gas is not as efficient as the conventional fuel, but this vehicle handles both fuels with no change in overall performance. There are no switches to throw; just gas and go.

I have equipped this vehicle with the necessary equipment for service in the volunteer fire service; not only does it look sharp, but its performance is superior to any other truck I have ever owned. Transmission shifting is smooth, and the power is unbelievable. I average over 16 mpg, which is outstanding for a vehicle this size.

It's a great looking vehicle that will still look top of the line for many years to come. I love this truck, and will run it as long as it will let me.

Faults:

Stereo rear speakers will not balance Doors squeak and wind noise Hood is so flimsy it 'oil cans' even on a smooth road GM service is nonexistent Seats are very uncomfortable after about 30 minutes.

General Comments:

Quality and fit are very poor especially for the price and customer service is nonexistent.

Faults:

Nothing, this has been one awesome truck so far, of course it is brand new with very little miles on it still.

General Comments:

It is a sierra classic extended cab 2wd with the flex fuel 5.3 v8. The motor is very powerful and fuel efficient. I love the fact that I can buy home grown e85 fuel for it and support our local farmers by buying the e85 fuel.
