Had my car (2018 M3 LCI2) booked in on Wednesday for an oil leak. No feedback the entire day until I called to find out what's going on. I was told the car won't be ready. Requested a loan vehicle and was told they don't have any. Left stranded at the office at 4pm. Only got my car back on Friday. If this is the way you treat your ///M customers, I dread to think how you treat the rest. Not impressed.
