Group One confirmed a symptom I was experiencing with an actionable repair that directly resolved my issue. The repair turned out to be vital and saved me thousands of dollars in future repairs. They were kind and accomodating and offered me a follow up appointment should I have any new dash lights that needed to be read or cleared. I feel utterly confident in their work and I felt well taken care of.

Excellent from beginning to end. Arranged to have my car picked up. Told me when it arrived at the shop. Called me when they discovered what the problem was. Told me what it was going to cost and when I could pick it up.
