My Mercedess E350 sunroof got stuck in open position and wouldn't close. After ruling out any mechanical and power issues, I took it to 3 or 4 Mercedes repair places that i have used in the past, including one dealership. All these places quoted me for $800-$1200 to completely disassemble the sunroof and said that even after that there is no guarantee it will be fixed and I may need a new one. Auto Germany guys spent about 45 minutes and fixed the problem, for a couple hundred Dollars. I really appreciated their knowledge and experience. These guys dont just rely on computers, they understand cars and troubleshoot using their knowledge and experience. I really recommend them!
