I recently leased a new Mini from Mini of Ann Arbor. It took me several months to actually make a decision and Kristin eventually assisted me with ordering a car with specific options from the factory. She kept me apprised of the progress of the build, shipping and delivery.
Prior to this lease, I had used the Mini of Ann Arbor service department for my wife's car and was quite happy with the service (and I'm almost never happy with dealer service, so this was a pleasant surprise).
Overall, a great experience
