Exceptional experience with German Auto Specialists Ltd! For over three and a half years, my 2012 Mercedes-Benz ML 350 had an intermittent Check Engine Light and low-idle wobble that multiple shops either punted on or tried to throw expensive guesswork at. John was outstanding on the customer side - transparent, professional, and clear with every update throughout the process. Lead technician Gus executed a masterclass in diagnostic logic and fault tolerance, systematically ruling out false leads until he isolated the exact upper intake manifold leak. It is rare to find an independent shop with this level of technical rigor, professional integrity, and commitment to finding the true root cause. Highly recommend John, Gus, and the entire team for specialized European auto care!
