A quick look at our past
O'Meara GMC is a Colorado GMC dealer with a long and storied history. Our founder, Al O'Meara, was named by Henry Ford as the first Colorado Ford dealer back in 1913, more than 100 years ago. Later, when Al's health failed, his son Al O'Meara, Jr. left Notre Dame to run the dealership when he was only 22 years old. The business has remained in family hands throughout its history and we became an authorized GMC dealer in 2018.
Our new GMC trucks
The GMC Sierra 1500 is one of the 10 best-selling vehicles of any kind in the country. It's available in a variety of configurations including single cab, double cab and four-door crew cab. Bed lengths range up to 8.2 feet and you'll have an excellent choice of powertrains including a muscular Duramax® diesel and two V8 engines. The GMC Sierra 1500 has a maximum conventional towing capacity of 13,200 pounds. The GMC Canyon is a mid-size pickup with a best-in-class maximum towing capacity of 7,700 pounds.
Our new GMC SUVs
The GMC Acadia is the most popular SUV that GMC makes. It comes with three rows that can seat a family of up to six and it offers fuel efficiency as high as 29 MPG on the highway. The GMC Yukon is one of the most luxurious passenger vehicles that GMC has ever built. It's a larger three-row SUV than the Acadia and the Yukon XL has an even longer wheelbase with more room for your cargo. The GMC Terrain is a compact crossover and It has the kind of comfortable suspension that your family will appreciate on longer road trips.
Save money with one of our quality used models
We offer an outstanding selection of used cars, trucks and SUVs including the GMC Sierra 1500 as well as the GMC Sierra 2500 HD. We're also an excellent resource if you're in the market for a used SUV like the GMC Yukon, Terrain or Acadia. On any given day, you'll find a number of our used GMC models are certified one-owner vehicles which means they're more likely to have had consistent maintenance from a single, satisfied owner. We also have first-rate used vehicles from other trusted brands like Chevy, Ford, Jeep, and Honda.
We're the home of affordable GM financing
We have a team of in-house financing specialists who can help you sort through your finance options and explain the alternatives in simple, understandable language. For example, a car loan allows you to build a cash value position in the GMC model you drive every day and eventually own that vehicle. Once that happens, you can say goodbye to car payments while you continue to drive that vehicle. You can qualify for financing from the comfort of home by submitting our completely secure online financing application.
