I have owed 4 GMC vehicles since moving to Boulder 5

Reviewed by JasonJanuary 15, 2026

I have owed 4 GMC vehicles since moving to Boulder 5 years ago, I wouldn't dream of taking them anywhere else. I was a GM dealer for 12 years and I know the struggles of finding good help. David in service is like family at this point. He gets my truck done quickly, cleanly, and they are super fair in their assessments and pricing. On top of all this, his communication and status updates are above and beyond the norm. I challenge you to find a better auto service department!

Dave Singh was my service representative. He scheduled my appointment for the day and time that I needed. The service was completed in a very timely manner and the car was washed.
