I have been taking my cars to Auto Centro for about six years now. They have taken excellent care of my old Audi A4, my BMW M3 my wife's Lexus LS400 and my Porsche Boxster S. I have recommended them to friend who have been very satisfied with their experience servicing Audis, BMWs and other Lexus vehicles. Auto Centro have a very reasonable hourly rate and are very honest about repairs which need to be done, should be done or just could be done. They do not try to sell you anything you do not need and always stand behind their work. They offer a free shuttle service to the metro or to downtown Rockville. I highly recommend bringing any make of vehicle to them for professional and courteous service at a very reasonable and highly competitive price. I have called other repair shops and dealerships after receiving quotes on service from Auto Centro and they are consistently 20% to 35% less expensive than other independent shops that specialize in German or Japanese vehicles and usually about 50% less expensive than the dealership.
