Used GMC for Sale in Fullerton, CA


While the used cars for sale in Fullerton can satisfy the needs of many drivers, we know that some folks prefer other types of transportation — and we’re not only talking about customers. For example, GMC doesn’t sell any sedans or hatchbacks but instead specializes in SUVs and trucks. That laser-like focus gives GMC vehicles a Professional Grade edge that sets them apart from other models, and owners can tell the difference. And it’s a similar story for the team at Car Castle. We also specialize in selling trucks and SUVs, so our honest and friendly sales staff has the knowledge needed to better meet your needs and budget.

Most of our used GMC trucks and SUVs come with free powertrain warranties as well, and all come with free Carfax reports so you can double-check their history with a trusted third-party source.

This quick review of GMC’s past actually starts with the Rapid Vehicle Motor Company. Founded in 1902, Rapid became known for building durable and reliable trucks that could satisfy hard-working business owners and other commercial customers. The Detroit-based company saw steady growth until 1908, when it was purchased by General Motors. Then renamed the General Motors Truck Company, which was shortened to GMC as time went on, the brand eventually established itself as a prominent player in the commercial-vehicle segments.

Success with “regular” customers began in the 1990s as consumer demand for trucks and SUVs began to increase. GMC responded with an increasing number of models aimed at retail buyers, highlighted by the 2002 GMC Envoy that earned some of the industry’s top awards. Nowadays, the GMC brand seems perfectly positioned for the 21st century with its premium portfolio of trucks, SUVs, and crossovers.
