Welcome to Baseline Auto Service!

Thank you for visiting our website. Baseline Auto Service has been serving the needs of Boulder (and beyond) drivers since 1990. In 2010, we moved from Baseline Rd. to our new location, 5729 Arapahoe Ave. Arapahoe Auto Sales, specializing in the sale of quality used cars, trucks and SUV’s was founded shortly after the move. We have also been a U-Haul Dealer since 1993, and have experienced staff able to assist you with all your moving needs, including truck and trailer rental, moving supplies and trailer hitch installation.

All our work carries a 12 month/12,000 mile warranty, as well as a Nationwide Warranty provided though our affiliation with NAPA Auto Care Centers. Our technicians are ASE Certified, which assures you of quality workmanship and the knowledge base and experience needed to properly diagnose problems.

We have a nice waiting area with television and free Wi-Fi if you would like to wait while we service your vehicle. We also have a courtesy van, and can offer our customers a ride home or to work within the city limits of Boulder.
