Here are the final tips from your BMW dealer in PA!
Ninth, if anything (and we mean anything!) at that shop makes you uncomfortable, do not hesitate to take your car to another shop. Maybe the diagnosis does not seem quite right, or maybe the staff members do not have enough time to answer your questions thoroughly, or perhaps the cost just seems excessive. Even if you have to pay a diagnostic fee for the shop to tell you what is wrong, it is okay to get a second opinion. Especially if the repair is larger or on any recommended repairs that has not been explained to your satisfaction.
Finally, after the repair work is done, you should ask for a written record of exactly what was done. The shop should be willing to explain exactly what work they completed, return any old parts upon your request, and present a detailed bill or invoice for your records. A good center will also provide written policy about warranties, refunds, and “come-backs”, meaning what they will do if you come back immediately because the symptom or problem you had has not been fixed or recurs within a few days.
Did we say finally? Well, we actually have a bonus tip! If the service was really good, say so! Tell the mechanics and your friends. Everyone likes to be praised if they do a good job. If the service center of even a particular employee gave you good service, tell them so. If they went out of their way to make sure you were taken care of , write a letter that can be posted publicly in their shop. Then, recommend that shop to friends and family and tell them to say you sent them
