This is a link to a thread here on the forum that gives a list of repair shops others have used. There is one in Fredericksburg and a few others in VA.
When looking for help with the Crossfire it is best to use an independently owned shop that specializes in European cars and know that the Crossfire is basically a Mercedes.
Most all mechanical parts are interchangeable with a Mercedes SLK 320 model year 2003 or if your car is supercharged a 2003 SLK 32 AMG.
