Edmunds' Expert Review

vehicle overview

Looking for a way to distinguish the GMC Sonoma from the pedestrian Chevrolet S-10, marketers have decided to sell the Sonoma as a capable alternative to the traditional sporty coupe. With an aggressive look, available sport suspensions, a third-door extended cab, snazzy Sportside bed and a strong 4.3-liter V6 under the hood, it shouldn't be a hard sell.

Despite this new advertising image, Sonomas can be fitted to suit just about any requirement, from strict utility hauler to off-road bruiser. Choose from three wheelbases, three cabs, a short box or long box in Wideside or Sportside configuration and two- or four-wheel drive. Then, you still have to consider three trim levels (SL, SLS, SLE), three engines (a four-cylinder or two V6 choices), a manual or automatic shift, and no less than seven different suspension systems-three for 2WD and four for 4WD models. Whew!

GMC substantially improved the Sonoma inside and out last year, so minor revisions were on tap this time around. Four-wheel-drive models, which already have four-wheel disc brakes standard, now get GM's AutoTrac, an electronic two-speed transfer case that detects wheel slippage and automatically directs power to the axle with the most traction-all at the push of a button. Other minor upgrades, such as new colors, bigger outside mirrors and a content theft alarm with remote keyless entry, round out the changes for '99.

With the high-output, 180-horsepower Vortec 4300 V6 on tap, and the ZQ8 Sport Suspension package, the Sonoma performs as energetically as high-priced sports cars did a decade or so ago. By any definition, that's progress. The Sportside box and sharp, five-spoke alloys nicely complement the top powertrain and suspension, turning the Sonoma into a true factory sport truck. If off-roading is your thing, GMC offers the Highrider, sporting a reinforced frame (four inches wider, two inches taller) and beefed-up suspension riding on three-ply all-terrain tires. The GMC Sonoma can outperform Ford's Ranger on or off the pavement, but when it comes to interior fittings, Ford still has the General beat by a wide margin.

Inside, Sonomas and Chevrolet S-Series pickups are virtually identical, with a roomy cab and modern dash layout. Center stack controls are canted toward the driver for improved access. Unfortunately, the cloth trim and carpeting feel thin and plastic used for dash panels and switchgear still looks as though it was sourced from Fisher Price. On extended cab trucks, an optional left-side access panel makes loading passengers or cargo into the rear of the cab much easier, but choosing the three-door cab eliminates one of the rear foldout jump seats.

For our money, the Ford Ranger, Dodge Dakota and Toyota Tacoma come across as more refined vehicles than the Sonoma, and their sticker prices reflect this impression. But in the compact truck value-per-dollar equation, GMC just might best deliver all the goods you're seeking-especially if what you're after is a sporty little truck able to sprint like a sports car off the line and through the twisties.

99 Sonoma SLS 4.3, v6, 4x4, 3 door
herb25, 3/31/2011
After going through 3 cars that did not last as long as they should have, I got this truck last year. It had 200000kms on it, the motor sounded like new. The previous owner did not replace the faulty gas gauge which meant changing the fuel pump. I ran out of gas twice before I learned and had the fuel pump replaced (the faulty sending unit is part of the pump). Also the passenger seat would not recline, a mistake at the factory so I bought a parts truck ( 2000 Blazer ) and took the seat from it. I got the truck for $6000, safieted and etested, but so far I have had to replace the rear brake lines, and 3 calipers, gas tank, fuel pump, and rad, signal light switch.
Great ride for a truck

I was surprised how this truck handles in corners, I didn't expect that GM has some great things in their products. Well built and very reliable
ZR2 Rocks
Tim, 6/8/2010
Got this truck with 90,000 miles on it. I have the 4.3 Vortec V6. Has 165,xxx now and still running great. Only replaced fuel pump and idler arms. I love the ZR2 (high rider) off road package and 4x4--never get stuck. It handles great and looks sharp. Great for outdoor activities (hunting, camping, fishing) and general all-around use. Love this truck. Reliable. Solidly built. Decent gas mileage. Fun to drive.
My GMC

I just bought a 99 GMC Sonoma a little while ago and I love my truck so far no problems or major mechanical stuff so far. I have always loved trucks. How they handle, engine etc and having an american made truck is even better!!
