1999 GMC Sonoma review: Our expert's take


The verdict:

Versus the competiton:

This is the unknown soldier in the GM truck lineup as the Chevy S-10 usually steals the attention.

Lots of good features, including optional third door ($295) on driver’s side for easier entry/exit into the back of this extended cab; push-button four-wheel-drive; passenger-side air bag on/off switch with an easy-to-see-light advising whether it is on or off; and enough cupholders for a family sedan.

The drawback is that there is precious little room in back even for an extended cab, and the one relegated there must use a jump seat. (Hmm, one jump seat but two cupholders in back?)

Ample power from the 4.3-liter, 190 h.p. V-6, which is rated at 16 m.p.g. city/21 m.p.g. highway.

Base price: $20,015. The test vehicle added 4-speed automatic for a whopping $1,070; air conditioning for $805; power windows/door locks/mirrors; remote keyless entry for $795; AM/FM stereo with cassette and CD player and clock for $402; tilt steering and cruise control for $395; aluminum wheels for $280; tinted glass for $115; and leather-wrapped steering wheel for $54. Add $520 for freight.

Get option-happy and the out-the-door price is going to approach that of the Blazer sport-utility.

Great quality

Great truck over all. Other then normal repair of a truck that's 12it years old and has 165000 miles everything runs great. I have a 4.3l engine and it is original engine and transmission. Drove from Toledo Ohio to Nashville and got 25 mpg. Suspension is my only complaint. It is a little soft as are many sonomas and s10s. I upgraded leaf springs and put air shocks on. Now it has no problem pulling a 21ft boat or carrying a load. Overall it is a very good truck.
