In 2012, employees at Grand Buick GMC Kia in Denver/Thornton, CO will celebrate GMC's 100th anniversary. In honor of this event, take a look back at some the auto makers' milestones.

In 1912, Rapid Motor Vehicle Co. merged with two other companies to create GMC along with General Motors. From 1912 to 1917, GMC produced the first electric vehicles. During WWII, GMC built 584,000 military vehicles. Their latest hybrid cars are only the most recent in a long line of amazing tech.

GMC produced motor homes during the 1970s as well. These vehicles were featured in the films "Stripes" and "Twister." One GMC truck became a recent slogan. HBO TV series "Eastbound and Down" featured a GMC Yukon Denali, and star Kenny Powers loved bragging about "Denali's on the reg."

The Sierra 1500 is the brand's top-selling model, and outsold competition vehicles in 2011 by well over 40,000 models. GMC and Denali trim levels "are among the fastest-growing nameplates in the US, with respective sales increases of 22 percent and 91 percent year over year," according to The Chicago Tribune.

In fact, if GMC were a stand-alone auto maker, it would be the 10th largest in the country.¹
