Thanks all for the recommendations about Mitch Carr's in Kensington, MD (Jim B+ in this thread and a few others elsewhere). Took my 420 into them for some specific issues and couldn't have been more pleased. They did a great job on the repairs I needed and took care of a few other things they found at no charge. Staff is really friendly and knows MBs inside and out. Sounds crazy, but I was so pleased I can't wait to save the cash to take my baby back there for her new timing chain and rails.
