I had my Cabriolet towed to German Motors of Salem because I did an oil change and a tune up on the car. After I did the tune up, my car started misfiring. I told Mike what had happened and he said that if it was something I missed he would do the job for free, if it was something else, he would charge me the hourly rate. He looked over the car, changed the wires around and timed my car in less than 10 minutes. He told me the mistake I made and gave me his card. I would recommend this company to anyone who has a german car. They are fast, reliable and competent.
