We took our mini in for an oil leak that seemed to have no origin, this was after having it looked at by another shop. They repaired what they knew was leaking and put dye in the system to locate any other leaks. We were still leaking oil from an unknown area after second visit, my husband talked to the owner and they agreed to bring it back for one more visit to complete the repair. They had it for a number of days, but they were able to locate the leak and repair it, finally I have no more oil in my garage. Thank you for being persistent, and making it right.
