Earl Duff Subaru in Harriman TN is a good bet, if you're in that area.
I can't remember the name of the dealership in Boone, NC, but, he was at the 10th Anniversary meet and owns 3 SVXes -- he is also a member of the Network. Just call and ask for John (the owner) and have him hook you up with a service man. Tell him "The SVX Network sent me." He'll take care of you.
