Ourisman World of Ford in Alexandria has always treated me well. Although they have yet to fix my intermittent starting problem because they can't verify it, they have always been straight forward with me and pleasant to deal with. The service manager I deal with is Jim McNutt.
I'm going down there on Saturday to drop my car off with them, so if you want to drive down with me you're more than welcome to. If not, he knows who I am by name so just mention I referred you.
The dealership main number is 703-660-9000. If you call and ask for Jim in the Service Dept, they'll usually forward you to just anyone in the Service Dept, so be sure to ask for him again when they transfer you. Its located on Rt.1 about 1 mile south of the Beltway, and I can usually make it in 30 minutes so its not too bad. Their work so far has been pretty good (as far as I have been able to tell, they've replaced transmission and done other normal maintenance stuff)
