had issues with my Z4, the roof wouldnt retract and there was no indicator lights. I searched online for solutions and i was given a lot of advice as to why it wasnt working. None of those solutions worked. I called the dealers and without looking at it they told me that the motors had to be replaced. I brought it down to German Motors on the advice of a friend and they did a great job figuring out what was wrong and no it wasnt the motor.
They were very friendly and polite. The only thing I had a problem with was the fact that there was no WIFI in the building. Which would have been nice as I had to wait and could have done some work.
The labor rates are good and I will be trusting my car to them in the future.
