I’ve used American Bus and Sprinter service in Annapolis for over five years. They are Sprinter experts. If you want Mercedes/Freightliner Factory service they are the best in the area. But they might be too far for you.
I have used Mercedes Benz of Fredericksburg for standard service and a some repair items (a new EGR valve, a couple of emission system sensors, failed glow plugs, and a failed drive shaft support bearing) for 8 years. The work has always been completed without issue. On my last service completed in June, I learned that my trusted/preferred technician, Cody, had departed. They currently have two Sprinter technicians neither with the Sprinter experience level of Cody. With this development there is an unknown factor and I hesitate to give them a full fledged thumbs up.
