The SMG light recently came on on my M3. I researched the issue and found out that replacing the transmission could cost as much as $7,000 or $8,000. The next morning, the car wouldn't go into gear, so I got worried and took it straight to the M Shop, where I had an oil change once before.
They were busy but agreed to fit me in and diagnose and research the problem. Turned out it was just a faulty relay. They had the part in stock and installed it for free. Total bill was $58 ($49 for the diagnostic testing, $9 for the relay). No problems since. I couldn't be happier, and will definitely go back.
Pros: Great service, honest
Cons: Busy
