our expert's take

The 2003 GMC Sierra Denali AWD four-door pickup may be the world’s most expensive work truck, with an as-tested price of $45,370.

While such features as four-wheel steering, a roomy rear cabin and a whopping 6.0-liter V-8 make it quite capable, this top-of-the-line pickup does not display world-class quality — certainly not befitting its luxury-car price tag, according to Paul.

On the other hand, Anita thinks the Sierra Denali is the best truck money can buy, and gives it her highest rating.

She: Here’s how I spent my weekend in the Sierra Denali. I went to every nursery in town, loaded up on mulch, topsoil and flats of impatiens. Every single person who waited on me would say, ‘Hold on a minute while I get some newspaper to protect your vehicle.’ And I’d always tell them, ‘No, I have a truck.’ But that’s only half of the story. Not only do you get the traditional truck benefits of haulability and hoseability, you get a vehicle with state-of-the-art steering — all four wheels turn when you’re cornering or parking — and you get a luxury cabin. Why is this not a five-star vehicle to you? Is it because you were laying on the couch while I was working?

He: OK, Farmer Anita, you’ve demonstrated your agricultural credentials. Now let’s talk nuts and bolts. You’ll get no argument from me about the capability of the Sierra Denali. The four-wheel steering is a truly remarkable innovation. Anybody who’s ever tried to back up a boat or horse trailer will be simply amazed at how easy that chore is with this new system. And that big 325-horsepower V-8, which makes 370 pounds-feet of torque, gives this truck more muscle than most of its competitors. I also think the exterior look is just about perfect — not tacky like the Chevrolet Avalanche or grotesque like the Cadillac Escalade EXT. It’s inside the cabin where the Sierra Denali starts to fall apart.

She: To call four-wheel steering a remarkable innovation is an understatement. It’s one of the seven wonders of the world, right up there with the Cuisinart. If this truck only had four-wheel steering and nothing else, it would still be worth five stars. I actually got emotional in parking structures. I was able to whip this 20-foot-long, 5,800-pound vehicle in and out of tight spaces as if it were a compact car.

He: Again, no argument. General Motors Corp. deserves major credit for that feature. I just wish the designers and engineers would have paid more attention to the cabin, where you spend an awful lot of your time. Granted, with the sole exception of Toyota vehicles, the interiors of GMC’s major competitors in the full-size truck segment have been equally weak. But that’s no excuse, especially on a vehicle that’s priced like a BMW 5-Series. I know you liked that gray woodgrain material; I thought it looked artificial and cheap. And there were other pretty noticeable flaws that would be unacceptable to anyone spending this kind of money on a luxury sedan. For instance, the plastic housing was pulling away from the outside edge of the driver’s seat. There were exposed screw heads in the rear armrests, and ripples in some plastic trim and rubber moldings. Sorry, but that’s just not acceptable.

She: My only problem was with the gigantic pickup bed and the overly heavy tailgate. The brainiac engineers at GM didn’t account for couch-potato husbands when they designed this truck. Surely, there’s an easier way to shut the tailgate than getting underneath it and heaving your shoulder against it or asking your lazy husband for help. And did I really need to crawl up under the fixed tonneau cover to retrieve my flats of flowers? I would like to see a cargo storage system that used the last third of the truck bed, so if you don’t have a full load, everything doesn’t slide too far forward and out of reach. I should also mention that, while the Sierra Denali is easy to park, that long bed makes it difficult to see when backing up.

He: When Ford brings its new F-150 trucks out this summer, with all the money and attention to detail they’ve spent on the interiors, I think the cabin in the Sierra Denali will look even cheaper than it does now. GM needs to spend some money and give its designers free reign to give this fine truck the equally high-quality cabin it deserves. Then the Sierra Denali will truly merit a five-star rating.

2003 GMC Sierra Denali AWD

Type: Front-engine, all-wheel drive, five-passenger, four-door pickup

Price (Includes $790 destination charge.): Base, $44,255; as tested, $45,370

Engine: 6.0-liter V-8; 325-hp; 370 lb-ft torque

EPA fuel economy: 12 mpg city/16 mpg highway

Where built: Oshawa, Ontario

Key competitors: Cadillac Escalade EXT, Chevrolet Avalanche, Chevrolet Silverado, Dodge Ram, Ford F-150, Toyota Tundra

12-month insurance cost (Estimated by AAA Michigan. Rates may vary depending on coverage and driving record.): $1,492

Paul’s rating: Acceptable

Likes: Same monster 6.0L V-8 as Hummer H2. Big-time towing capacity. Lots of room in rear bench seat.

Dislikes: World’s most expensive work truck unfortunately does not have world-class quality. Fake wood looks cheap, inferior. Lousy fuel economy. Plastic housing pulling away from outside edge of driver’s seat. Exposed screw heads in rear armrests. Ripples in some plastic trim and rubber moldings.

Anita’s rating: World Class

Likes: Classy-looking gray woodgrain material in cabin. Best of both worlds — a true workhorse with the interior of a luxury SUV. Nicely equipped rear compartment, with cupholders, vents, audio controls. Four-wheel steering makes parking amazingly easy. Love the no-nonsense truck styling.

Dislikes: No adjustable pedals. Tailgate is too heavy. Difficult to see when backing up. Had to crawl up under fixed tonneau cover to retrieve flats of flowers.

  • Transmission went out at 50,000 miles.

    Transmission went out at 50,000 miles. Rack and pinon front end went out before warranty was up dealer would not cover it. Engine been sputtering and burning anti freeze for years can’t go long distance for fear truck won’t make it. Body all rusted up for no good reason never went out in snow because 2wd drive couldn’t get out of driveway. Never could pass inspection when it was new cost hundreds to get evap system replaced due to another lemon system on truck. Then the power steering system cooler which is another gimmick cost more than the power steering pump to replace. Just a useless add on to cost people money.

  • Am I the only one that has had the instrument panel

    Am I the only one that has had the instrument panel completely fail? Mine did YEARS ago. So why is my reliability rating 5? The computer still works, I know how fast I'm going, the Miles remaining on the fuel economy is accurate, and it runs. Everyday. Replaced one hub and bearing, water pump, starter, ignition. A/C doesn't work, but I've got windows (which work if you know exactly where to push the button.) Oh, and the Engine light is always on, because the throttle body really needs a thorough cleaning or replacing. Motor and transmission have been crazy reliable for 20 years on truck bought new October '0 3. Nothing a few hundred dollars wouldn't fix. Though there are several of those, they don't keep me from getting from A to B.

  • Best truck, so good I’ve got second one

    Bought truck brand new with 9 miles on it other than two water pumps and one fuel pump which were my fault for running on fuel. I haven’t had any complaints other than the guy on the dash peeled off minimal 53 runs great at 200,000 miles reprogrammed truck at 500 miles gets 20 to 22 miles a gallon down the highway as long as you’re on supreme runs great never left me stranded best truck I’ve ever owned I’m in search of another one similar same body style, but a three-quarter ton now but plan on keeping this is long as I can just purchased a brand new 5.3 to put in it when this one wears out it’ll keep going had minor issues with the dash gauges, light one out and a couple of gauges. No big deal, I also have an 03 Chevy Tahoe but it had all of the problems in the Insta rebel had panel replaced $600. No other issues. Great track Holly

  • Hated this truck

    Nothing but issues. Owned for less than a year and 30L60E Trans went out. Spend $2000 to replace that. Then a bunch of wiring issues, including the dash. Dash stopped working so I would have no idea how much gas I had, how fast I was going, etc. Got a speeding ticket from the stupid thing because I wasn't sure of my speed. 4x4 switch had issues. Nothing but problems. Worst vehicle I had ever owned.

  • Reliable As Can Be

    Bought my 03' Sierra 1500 as a first vehicle. It was an extended cab with the 5.3 litre Vortec. After 245,000 miles I have had VERY FEW ISSUES, though I am the second owner and don't know of any issues prior to my purchase. During my time with it, I have only had to replace the 4X4 actuator ($500), headlight bulbs (typical), ball joints, and the rear U joint on the driveline. The motor has given me ZERO problems nor has the transmission. The interior has held up well with only a few small things like the coating on the dash peeling (has been very minimal). Only complaint is that the 5.3 litre is a little underpowered. I find that it frequently has to downshift when ascending in a canyon on a light gradient. However, this could be in part due to the age and milage on the motor. Overall I rate this vehicle as excellent!

  • Not as advertised

    The picture the dealer posted made this vehicle sparkle! When I got there to test drive it, not so much. It was dusty and dirty. There was a spot 9-12 inches on the hood where the paint was damaged. I started it up and the check engine light was on. When I asked they told me the knock sensor was out but they had one on order and would put it in. I drove 75 miles to look at and test drive this truck and was very disappointed.

  • Nice Truck

    This truck would have met my needs. I really like the exterior color of the truck. I'm not real big on leather interiors but it wasn't in too bad of a shape for being a 2003. Both the driver and passenger seat were electric with heated seats and position memory for 2 settings. The owner was not very willing to negotiate otherwise I would now own this truck.

  • This truck died before it reached 100k.

    I never owned a vehicle that did not make it at least 100,000 miles. The transmission stopped working. The instruments on the dash worked sometimes and sometimes not.

  • 200,000 MILES & COUNTING

    I have over 200,000 miles on the 5.3 in my truck and it is still running like it was new. the underside has almost no rust. The gearing is decent as it barely turns 2000 rpm at 75 mph. (Mine has the 3.73 rear end ratio) Fuel economy isn't great at 17 mpg highway but it wasn't built for economy. All around a great truck. the interior is almost brand new in appearance.
