BMW Dealership (now an Autonation monster) repaired BMW Recall items then diagnosed issues with drive train. One issue they diagnosed was INCORRECT! Calling it only a valve cover/oil leak when in fact the main leak was the transmission. That's a huge miss. Bertini's not only diagnosed the proper issues, they were 35% lower cost for the Dealership items quoted for repair. Prompt, courteous, they take good care of your vehicle and are 100% KNOWLEDGEABLE in what they repair. I found Bertini's after working with 4 BMW independent repair shops in Auburn, CA. Bertini's is well worth the drive and will not go to anyone else.
