It was my first time at this shop and I wish I knew about it before. Yesterday I dropped off my car cause it was running rough for a while now. I have 180,000 miles in my Mercedes and I didn't expect a significant improvement. But when I picked it up my car was as smooth as when I bought the first time, I couldn't tell if it was on or off. I was really impressed with the work, they did, the professionalism of the team and the cost was reasonable. This will be my shop from now on. Thank you guys.
