Very friendly and professional, shop and waiting room was very clean and well kept. They called me the first day (I accidentally brought it in a day earlier than scheduled and they still accommodated Me) with a list of recommended repairs that included a fuel pressure sensor and catalytic converter- which they fixed without issue - everything for the agreed upon price. I really wanted this to be my shop for the foreseeable future. Up to this point - excellent. Unfortunately, when I received my vehicle not all of the work was completed after two full (technically three) days. A simple rear brake light issue was not fully fixed and or diagnosed and tested. Again, they say it was, so I have to take their word for it. The end result is that a persistent brake light error remained. In addition, a replacement oil cap that was recommended and installed by them leaked all over the engine. I won’t make assumptions as to how or why that happened. It left me going to a Mercedes’s dealership on a Saturday morning after I noticed an oil burning smell and found a puddle of oil under the vehicle when I arrived home Friday night. I had to borrow a car and buy an actual Mercedes oil cap and gasket from the dealer by VIN that fit securely and did not leak. It also left me completely degreasing my engine bay and garage floor since almost a full quart of oil leaked out. To their credit, they did call me back immediately on Monday morning, offered a tow service and to take care of it all. Since I had already fixed it, that was unnecessary - again to their credit - they also did offer to reimburse me for the cap. Again not worth me driving there to handle. The cause of the leak is assumed by them to be a faulty part-we will never know. They also claimed to have road tested it after the repairs. Again, I have to take their word for it. Unfortunately for me those all add up to too much of a coincidence and chain of errors. Maybe you will have better luck. Mine appears to be an anomaly. The other stellar reviews by loyal customers that convinced me to try them appear genuine and sincere. They did allot right and got 80% of it perfect. As for the other 20% I will not be returning.
