Wow, this place got bashed by others. Everything that we experienced was great. I had no appointment and stopped by on a Thursday morning. Our Service Consultant, Derrick, explained that they were busy, but that he would help as best he could. That he did.
We needed some warranty work done and Derrick wrote us up right away. We were lucky enough to get a MINI loaner, without notice mind you. When the work was finished, the following day, I received a courtesy call from Derrick. Due to work I was unable to pick up my car until the next day, which was no issue at all.
Thank you Derrick, and thank you MINI of Tempe. I hope our next visit is as accommodating.
