Our Buick had an engine light on and was running very rough. Gill's took the time to conduct a very thorough investigation and found a few issues. The cost to repair was fairly significant, so we had just what was thought to be the main culprit fixed and we would address the rest of the issues as needed (fairly old vehicle). The sticking valve was replaced and the car drove normal and the engine light was now off. The price seemed high, but you get what you pay for. These guys have a top notch garage with very experienced staff. I have a pretty solid background from working on cars for 30 years, and the issues were explained to me very clearly. I was very happy they let me ask my dozen questions with out making me feel "they were the experts, just listen to us" attitude. Very professional people and will continue to bring my bigger car issues to them!
