What Our Customers Say

Denver, CO

I discovered Firos Auto Haus by accident when the engine light on my car started flashing, the engine itself was misbehaving and I was on I25 heading home to Colorado Springs. They were great! Knowledgeable, helpful, and generous. They went the extra mile to phone the dealership to see what was covered so that I didn't have to spend unnecessary money. They even added oil to my car as a gift and made it possible for me to return home safely. I would trust them and use them consistently if I were in Denver.
