German Motors is absolutely the BOMB. I've been using Mark and his team at German Motors since 1992. The service is superb, the work is impeccable, and everyone is always friendly and helpful. So I show up today with my 2001 ML320, and a detailed explanation of my exact problem. "It's running like crap and the check engine light is on." A few hours later I get it back and it's smooth as silk! Mark kept my last ML320 running well through 240,000 miles, and it's still running. I drive from Boulder to Lakewood to use them because I can trust Mark totally. He'll always give me a detailed list of issues, cost for each, which need to be addressed right now, and which can be handled later. Had a problem on a road trip a couple of years ago, and went to a supposed MB expert who was having problems figuring out my trouble. I called Mark, got the 'expert' on the phone with him, and he walks the guy through the issue and how to fix it. Sweet! Even hundreds of miles away he's keeping me going and saving me $$$$. If you're a MB owner, you *really* need to give these folks a try. You simply won't find better, but you can sure spend more trying.
