I brought the guys an ancient MB E-class with a very oddball problem. We decided, collectively, to not chase it endlessly. The 1st Class guys' thoroughness, thoughtfulness, honesty, and communication were beyond reproach. When the work went past schedule, I was even provided with a loaner car.They also did some nice little extras that I wasn't expecting. For instance, there is insulation under the hood that had come unglued. They fixed that. What a nice surprise.I'd definitely come back. I'm someone who does a lot of DIY stuff, but for when I'm in over my head, these guys are a great place to take a Mercedes to. They have a lot of integrity.
