2007 GMC Sierra (Classic) 1500 Extended 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 Significant About This Car?

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

Driving the Sierra (Classic) 1500 Extended 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.

Interior

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.

My Baby

"This is my first GMC truck I have ever purchased, my first GMC in any vehicle. I have had nothing but good service out of it. It had 182,745 miles on it when purchased, it has 201,779 now. I have replaced the windshield wipers, water pump, fan belt, and tires and that's it. The water pump I expected to go out just maintenance. This truck is the easiest truck to work on, never seen anything like it. Parts are easy to get, and fairly priced. It doesn't use oil, and gets EXCELLENT gas mileage. I have had Chevrolet, Ford, and Dodge trucks before, but none compare. I like the body style as it is a 4 door, but appears to be a 2 door, the back doors open in the suicide manner. Cool!!!"

"My first truck.I bought this truck a year ago to tow my 4000+lb. cars to shows and the drag strip. I only planned on using it occasionally, so I didn't want to spend a fortune. Took a chance on an 11-year old truck with 206K miles, and I got lucky. The good stuff: My first trip was 3000 miles round-trip, towing over 6500 lb. No problems! I don't drive slowly, and the 6.0 liter had plenty of oomph. Had to downshift going over some mountains, but on the level I forgot there was a trailered car behind me. Comfortable leather seating, everything worked great (except oil pressure gauge). Maneuverability with Quadrasteer was really easy. Several weeks later I made a 1000 mile trip, again no issues. You'd never know this truck has so much use on it. The not so good: Body rot in the rocker panels. Replacements are cheap except for labor (if you can't do it yourself). Corrosion in the rear brake line. Be certain to check it out. Bad oil pressure sending unit. Cheap fix. I love this truck!"

"I owned a 200 2500 hd, then purchased the 2003 2500. I loved both of these trucks. The 6.0 has plenty of power however it does suck the fuel down. Average 10 mpg. towing or not, loaded or not. Both of mine where the 2 wheel drive versions and very bad in the snow used to get stuck all the time, snow, mud, wet grass. I will be buying another just 4x4"

Likely to recommend this car? (1-10): 10

"I bought this truck new in 10/98. It has over 160K on it and it is still going strong. this truck does not get babied, but it is not abused. I use it for hauling firewood/wood pellets/ATV, I load it down when traveling and hunting and it is used to tow a travel trailer multiple times a year. Living in MT, it gets used off-highway about 1/3 of the time and has served me well. It has had regular scheduled maintenance and other than that new tires, rear breaks and front bearings. Transfer case did go out @ 100k but replaced with a rebuilt and have had no trouble. Does alright mileage wise if you keep your foot out of it, but poor mileage towing - it is a truck after all. Even at 160K it does not lack horsepower for towing in the mountains."
