The Sonoma has faithfully served the GMC line and its customer base. For the last decade, the Sonoma has fought to compete with many new rivals that offered more power and room, but rarely as much content for the money. With the arrival of the new Canyon pickup, the Sonomas burden is finally relieved and the line will probably soon be sent to greener pastures. For 2004, the only body style available is the four-door Crew Cab, though there are still a number of trim and option packages from which to choose.
The base Sonoma model is now the plush SLS trim. To further distance the Sonoma from its Chevrolet cousin, the S10, all two-wheel-drive Sonomas now feature a standard 60/40 split-bench seat. This year, GMC has created a ZR5 Sport Appearance package that adds side steps, a roof rack, brushed aluminum bed rails and 15-inch alloy wheels. The Sonoma also offers an extended bed option on the regular cab pickup that increases the vehicle's gross weight capability to 4900-lbs.
The base 2.2-liter four-cylinder is adequate for moving the truck to and fro, but is not the best choice for anyone using the pickup to do the work a truck is intended to do. If money is not too tight, opt for the 4.3-liter Vortec V6; its 190-horsepower and 245 lbs-ft of torque give the Sonoma the heart it needs to perform as a first-rate compact pickup. As with the S-10, you have your choice of a standard 5-speed manual or 4-speed automatic. Four-wheel drive models employ a simple push button shift-on-the-fly system and on 2WD models, you can opt for a locking heavy-duty rear differential.
Though the Sonoma shares its interior with the S10, the GMC touch can be seen and felt throughout the cabin. The SLS Crew Cab comes with a standard leather interior that is stitched loosely to create an elegant pattern. Standard equipment includes air conditioning, anti-lock brakes, illuminated entry, AM/FM stereo with CD, intermittent wipers, tachometer, oil and volt gauges, dual mirrors, auto headlamp control, alloy wheels and a leather-wrapped steering wheel.
