2007 GMC Sierra (Classic) 2500 HD Regular Cab Review

By

You can thank the Coca-Cola Company for attaching the term "classic" to a product that should actually be termed "old." The latest company to grab hold of this scheme is GMC. With the arrival of the all-new Sierra, the previous model forgoes mothballing to become the 2007 GMC Sierra Classic. A capable pickup truck by all measures, the Sierra Classic continues to offer a full range, including 1500, 2500 and 3500 models in Regular Cab, Extended Cab and Crew Cab configurations. Despite the Sierra Classic's age, it can still pull, haul and luxuriate with the best new rivals from Dodge, Ford and Toyota.

You'll Like This Car If...

If you need a serious work truck, one that can haul loads of dirt or tow a horse trailer, there is a Sierra Classic with your name on it. The Sierra Classic's interior can be made quite plush, especially with the Denali trim level.

You May Not Like This Car If...

If you are not used to piloting a large pickup, the Sierra Classic may be a bit too much truck for you. The Sierra Classic also lacks such newer conveniences as GPS navigation and side-curtain airbags.

What's New for 2007

Entering its final model year, the Sierra Classic receives standard recovery hooks on 1500HD, 2500HD and 3500 trim levels.

Driving the Sierra (Classic) 2500 HD Regular Cab
Driving Impressions

On the open road, you'll find the Sierra's steering is light, with modest feedback to the driver. On the other hand, the brakes get excellent marks for their rock-solid pedal...

... feel. It should be noted that different wheel and tire packages will affect the way the Sierra feels on the road, so you may want to test-drive something that will reflect your final choice. Choose the available 5.3-liter V8, with 295 horsepower and a stump-pulling 335 pound-feet of torque, and you'll find that even a fully-loaded Sierra with a trailer attached can accelerate and pass without much hesitation. When not burdened with a heavy load, the Sierra's performance is practically muscle-car quick, especially when accelerating from a standing stop. The four-speed automatic transmission delivers crisp, precise shifts, and features a tow/haul mode that limits gear hunting when towing or driving in mountainous or hilly terrain.

Hybrid Drive
An electric motor mounted between the engine and transmission helps get the Sierra Hybrid trim rolling, saving gas as well as wear on the engine.

Denali Trim
The luxury-oriented Denali Crew Cab is a step above the SLT trim level.

The Sierra Classic's interior is nice, but starting to show its age. There is a lot of dark plastic on the dash face, and the plastics and other materials used on the dash and door have a generic look. Denali models get a bit more color and contrast with their trim and interior fabrics. The Sierra Classic's seats are soft but comfortable, especially when covered in leather. Those who regularly carry two or more people will want to get the Crew Cab for its roomy rear seat; the Extended Cab is best used for short trips or to provide a secured storage area.

Exterior

GMC has tried to distance its trucks from their Chevy counterparts with a bold grille design, different wheels and the upscale Denali trim option. The Sierra Classic maintains that tradition with a boxy middle section tempered by rounded edges and the familiar GMC logo proudly centered in the grille. Though older than the F150 and Dodge Ram designs, the Sierra Classic still strikes a powerful stance, especially when outfitted with the Denali trim package.

Notable Equipment
Standard Equipment

Base SL models have cruise control, CD player, air conditioning, tilt wheel and chrome-styled steel wheels. SLT and Denali models get a four-speed automatic, electronically controlled transmission with overdrive and tow/haul mode and a 4.8-liter V8 or 5.3-liter V8. Other models can be equipped with engine choices that include the 6.0-liter V8 and the 5.3-liter hybrid.

Optional Equipment

Options for the Sierra are too numerous to list. Beyond the various bed lengths, wheelbases and cab configurations, you can opt for the StabiliTrak stability management program, a number of off-road and towing packages and the OnStar telematics system. SLT and SLE Extended Cab two-wheel-drive models can be outfitted with a new Performance Edition package that matches a 6.0-liter high-output Vortec V8 with 20-inch chrome wheels, high-performance suspension, 3.73 rear axle, automatic locking differential and traction control.

"I love my truck very much. I do a lot of heavy hauling and it has done a great job. I have had no major breakdowns at all. I have replaced the break lines but that is minor and expected after 250k. I am buying a newer one because of the hard work I cant afford for a truck to break down when I am working."

"I've owned this truck since new and will buy another GMC truck next. Very reliable. I had to replace a couple alternators, a water pump and a fuel pump. Not bad for 200k miles and still going strong."

"With the current price of a new pickup, the mileage I'll get out of this truck. The price of jeep wrangler with the jeep transmission problems. All other vehicles new price consideration how long they last. I could not afford to sell it for less than $69,995.06 . The one I had before was a 1998 Chevy I had 298,476 miles on it when some guy made a left turn right into the front end. Totaling My pickup another small SUV plus his vehicle."

"Other than body dings, going over a creek embankment into an unseen solid metal item and a very angry bull... this truck has been indestructible. I get about 18.9 mpg on the highway, hauling big trailers drops it to 15-17mpg depending on stops and starts, but that city hauling sucks the diesel. The torque in this bad girl is her crowning jewel. I have owned this one since 2008, bought new and have NEVER managed to get her stuck, and I stuck the bronco, the tractors, the 1500 I had and the neighbor's tractor... this one is my favorite truck and I get offers from people wanting to buy her all the time."

"I purchased this truck new. I have always owned Fords but decided to try GMC. Glad I did! Better build quality. Better ride. Better handling. Better fuel mileage. I replaced the factory air filter with a K&N and now get 22mpg on the highway. I run Mobil Synthetic oil and it makes a difference. 183000 trouble free miles. Just general maintenance and brakes. Oil change every 5000 miles. Still runs great. I tow my tractor with bush hog and a cattle trailer with up to 10 cows at a time in it no problem."

"I have owned this truck since 2002. Overall, very reliable thru the years and still runs great. My only beef is with the rust issue with GMC and Chevy trucks of this era. 99% of the trucks I see have the rust problem over the rear wheel wells and along the running boards under the doors."
