GMCs are premium vehicles that, unsurprisingly, often come with premium price tags. But you can still save a significant amount of money on the brand’s SUVs and trucks simply by shopping in the pre-owned marketplace. That’s where you’ll see depreciation in action. The bottom line is that because of depreciation, the typical one-year-old used cars for sale in El Cajon can be some 20% less expensive to buy than comparable brand-new models. When comparing five-year-old models with the new versions, depreciation can then mean a price difference of 60% or more. Further, you’ll save extra money on car insurance, since premiums are usually less for older cars as well.

Of course, Legacy Cars is just as focused on reliability as it is on affordability. So we only choose the best-quality used GMCs for our inventory, and each one is then carefully inspected and checked for safety. We even put our used vehicles through smog checks to make sure they pass California’s strict guidelines for emissions. We also offer extended warranties for additional peace of mind.

Whether you visit us at our clean and convenient showroom or browse our online inventory, Legacy Cars is waiting to help you find the used GMC of your dreams.

Although passenger cars get most of the press, motorized commercial vehicles have been an important piece of the auto industry since the very start. In fact, the Rapid Vehicle Motor Company — which evolved into GMC — was founded in 1902 in the Detroit area. Rapid quickly earned a reputation for building durable and reliable trucks, and that didn’t go unnoticed by the executive team at General Motors. GM bought Rapid in 1908, transforming the latter company into its own in-house commercial-vehicle division. The new brand was first known as the General Motors Truck Company, which was shortened to GMC as the years went by.

GMC began crossing over to “regular” customers in the 1990s as retail demand for trucks and SUVs began to rise. The brand’s appeal — and its vehicles — became so strong that the GMC Envoy was named the 2002 Motor Trend Sport/Utility of the Year. Nowadays, the GMC brand seems perfectly positioned for 21st-century success with its premium portfolio of trucks, SUVs, and crossovers.
