Allegiance Automotive: Quality Service and Repair for Your Vehicle

At Allegiance Automotive, we are not only passionate about classic car restorations, we are passionate about every single client understanding the issues at hand and the repair needed, whether it’s on their truck or on their vintage car. It doesn’t matter if you are not a car enthusiast, an engineer, or just not familiar with any of the terms we use. We want you to stop feeling like someone is fixing too much or explaining too little just because you might not know the difference. You will walk out of our shop confident in the state of your vehicle and understanding what you paid for. Trust only works if it goes both ways.

We work together in partnership with you to keep your vehicle running safely & reliably as you, your family & friends roll along and through the front range and mountain roads of Colorado. Just take a look around our Boulder shop the next time you stop by and you’re bound to see all makes and models up on the lift getting anything from an oil change or basic tune up to a brake job, complete engine rebuild or a performance package added to the machine. Have a conversation, ask anything you’d like to know. We hope to see you soon!

What does it mean to be ASE Certified?

Certification is earned through training and testing by the National Institute for Automotive Service Excellence, a non-profit organization founded in 1972. More than 300,000 automotive professionals nationwide have earned this designation, including Allegiance Automotive in Boulder Colorado.

This ASE designation means that your car care specialists at Allegiance Automotive recognize how rapidly the mechanical operations and technology supporting the proper running of your vehicle changes. Staying on top of those details is essential to proper care and maintenance of your family cars & trucks. As your trusted automotive professional team, we are committed to meeting that test with our ASE Certification status.
