GMC's mid-size Sonoma blazes into 2001 with a new four-door model, a Crew Cab sporting four front-hinged, full-size people portals. GMC will sell four-door Sonomas only with a V6, automatic transmission, and four-wheel drive, and only in the top two trim levels. So you could almost think of the Sonoma Crew Cab as a comfortable sedan, with off-road capability that just happens to have a pickup box out back. Almost. The rear passenger compartment is tight and the bed is just four and a half feet long. The full-line of more economically priced Sonoma continues. Those in the market for a cost-effective midsize pickup should be able to find a variation on the Sonoma to serve their needs. A quietly handsome appearance, healthy V6 torque, and a myriad of options all argue in the Sonoma's favor.
