I am the proud owner of my dream car that I've wanted for over 20 years. As you can imagine, now that I own it, I'd do anything to make sure it runs beautifully. I needed to have some work done, I called around to several BMW shops around Tucson. I called Group One and spoke with Mark. After a delightful phone conversation, and him telling me what I needed to know and an approximate estimation of what my repairs might cost, I decided to make an appointment. Upon my arrival at the shop, Mark was there and greeted me. He assured me that as soon as a proper diagnosis was made that he would give me a call with all of the details including the cost. 2 hours later, as promised, I had my call. The repair cost was far less than I had been "approximately" quoted by another shop in town. By the end of the same day, I had my precious baby back and running better than ever! I am so happy with Mark and Group One that I will not hesitate to call if I ever need anything done in the future. This is a place where you can feel safe and comfortable knowing your car will be taken care of. To top it all off, I was able to have a loaner car for the day. Now that's SERVICE! Well done, Group One!
