The Sierra gets a revised look this year that includes a new front fascia, revised side moldings and optional multifunction, fold-away mirrors. On the inside, GMC has added new seats, a more comprehensive driver information center, a redesigned instrument panel and optional dual-zone climate control and satellite steering wheel controls. 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. Other upgrades include an improved Insta-Trac part-time four-wheel-drive system for reduced service costs, a more efficient starter for the 8.1-liter V8 and a revised headlight switch that allows drivers to turn off the daytime running lamps.

Great Truck

tdorsett_1,03/03/2003

Hauling hay and horses has never been so easy, power to spare, better on fuel mileage that I would have though. Pulling a small 2-horse slant load trailer with two 1200 lb. horses or a twenty-foot trailer loaded with three round bails of hay, I get an average of 18 miles per gallon. Without pulling, I get between 21 and 25 miles per Gallon. (Highway)

Proffessional truck!!!!

Should I lease or buy a 2003 GMC Sierra 3500?

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.
