I am loathe to have to give them a single star. Bought my 2004 mini from them in 2006. Went in to have the oil changed, ended up with a bill for $1600 for everything they discovered wrong with my vehicle while they were changing the oil. Never went there for servicing again.
Cut to earlier this year, my power steering started going out when I was driving the car. *SCARY*.
Turns out there is a warranty extension on the pump (mini cooper knew it was faulty... http://www.motoringfile.com/2013/06/01/power-steering-warranty-extension/), and when I took the car to get the part replaced, we were told there were going to be other parts to be changed and that would NOT be free. They were explicitly told NOT to do anything but fix the faulty pump.
They called an hour later to pick up my car. I get there and was told there was no indication that the part was faulty and they would not replace the pump.
I asked the salesman point blank, "So you're going to let me drive a dangerous car? You're not going to fix it?" He simply replied that there was nothing in their tests indicating the pump was faulty.
I ended up selling the car to a company that would fix the pump themselves.
Bottom line: they let me drive a broken car in dangerous circumstances and did not care that my safety was in jeopardy.
Just think about that before asking yourself if you should buy a car from them.
