Powerful drivetrains, classic exterior styling and unique options make the Sierra a pickup worth considering, but Fords new F-150 has it beat when it comes to interior design and overall refinement.

2003 Highlights

The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and an additional wheel design. Top-of-the-line models get power-folding heated mirrors with puddle lamps and turn signal indicators. Inside, the Sierra now offers a Bose stereo system and XM Satellite Radio. The instrument panel and center console have been redesigned, and GMC has added new seats, a more comprehensive driver information center, optional satellite steering wheel controls and a dual-zone climate control system. For increased safety, Sierras now feature a standard front-passenger-sensing system and dual-stage airbags. All 4.3-liter V6-equipped Sierras and California-emission V8s are now ULEV certified, while electronic throttle control is now standard on all V8 engines. Finally, the Autotrac four-wheel-drive system has been modified for less intrusiveness at low speeds, and the brake system received upgrades that provide better pedal feel and improved overall performance.

Best Truck on the market

Russell,06/16/2009

Original owner. 130k miles. RELIABILITY-I've only had 2 problems, and 1 (speedometer) was a recall. The catalytic converter went out at 115k, but other than that, no rattles, no squeaks, not even a brake job. Overall reliability is good, better than my Toyota Matrix. DRIVETRAIN-GM says this V6 has less HP than Ford's, but this pickup (w/3.42 rear end) sure feels stronger than my

Great Truck

Jason 95834,03/04/2003

I have taken all the makes for this type of truck for a test drive, and this truck was the one. The GMC has the best handeling/comfort, good power and excellent seats and interior(did not look tastless or cheasy).Hardly any wind noise and no annoying vibrations. Build quality I am most impressed with. Someone in a Mustang t-boned the truck on the drivers side and

Couldn't ask for anything more.

rustysmith,03/03/2009

6 years later, I'm still happy with my purchase. It's been a great truck with no worries. The only problem I've had is not getting the speedometer fixed before the recall ran out. My own fault. Other than that, only oil changes for over 120k miles. Reliability on these trucks is second-to-none. I have three friends with the same body style (one '04 and two '05's) and all have over 100k

Should I lease or buy a 2003 GMC Sierra 1500?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
