Chevrolet Silverado I: 1999 to 2007

Chevrolet Silverado I is the first-generation range of trucks manufactured by General Motors under the Chevrolet brand. This model was first manufactured in 1999 and it continued till 2007. This is a fairly old truck model, but you can still spot some of them in the market. Chevrolet Silverado I is a full-size pickup truck that was first introduced in the late 90s. They featured a classy look and was made for light-duty purposes. These light-duty trucks were available in three cab lengths. For the first year, the company released only the regular cab and a 3-door extended cab model. In 2000, they added a driver’s side door option in the extended cab. This means the car had four doors. It was equipped with a 5.3-liter engine. In 2003, the makers introduced a rework version of the Silverado. This time they had to change the front and also made a few changes in the rear. In 2006, the truck received a facelift which was similar to the HD version. Chevrolet Silverado trucks are powerful and come with a lot of features. The Silverado series are run across four generations, before the company stopped production.
