About Us

Our Mission at Boulder Auto Sales and Service is to consistently provide you with quality auto sales, service and repair, at a fair price with customer service that will exceed your expectations.

Boulder Auto Sales and Service, formerly Baseline Auto Service located at 2830 Baseline Rd, was founded in 1990 and has been providing our customers with quality auto care for over 20 years. In 2010 Baseline Auto Service moved to our present location, 5729 Arapahoe Ave. In 2015 Baseline Auto Service was re-named Boulder Auto Service. In 2018, we added high-quality auto sales to our facility and now operate under the name Boulder Auto Sales and Service.

Sarah Quillen has owned the business since 1999 and continues as owner and dealer of Boulder Auto Sales and Service. Our entire team, including our ASE-certified technicians, take pride in the work they do, and strive to be certain that their work is done right the first time.

All service work performed at Boulder Auto Sales & Service carries a 12 month/12,000 mile warranty along with a Nationwide Warranty provided through our affiliation with NAPA Auto Care Centers.
