With its powerful engine lineup and revised interiors, the heavy-duty Sierra makes a strong case for itself against the competition, but questionable build quality keeps us from calling it best in class.

2004 Highlights

Base trucks get upgraded via newly standard cruise control, chrome wheels, chrome rear bumper and chrome grille surround. The SLE trim adds foglamps to its generous list of features. The Work Truck Package (with unique grille treatment) is now available on all models. Lastly, a trio of new colors, Sand Beige Metallic, Silver Birch and Sport Red Metallic debut.

Absolutely the best truck I have ever owned. During it's maiden break-in run I got 23.8 mpg. When engine is broken in mileage should be even better. I drive between 55-65 mph and this seems to be the "sweet spot" for performance. Got it to haul our slide in camper and this will be no problem now.

Should I lease or buy a 2004 GMC Sierra 2500HD?

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.
