Edmunds' Expert Review

Why buy more truck than you can use but settle for less than you need? The GMC 2500-series light-duty Sierra exists for those who want a truck that slots between the 1500 and the heavy-duty trucks.

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. On the 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. On the hardware side, the standard 6.0-liter V8 gets electronic throttle control, as well as the ability to run exclusively on compressed natural gas (CNG) or a mix of CNG and gasoline. 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.

Should I lease or buy a 2003 GMC Sierra 2500?

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.
