Your best bet in Fredrick, MD is Criswell in Germantown, MD, near the DOE. I've been there, talk to Marcio or Chris, probably best Chris, tell him I and the EVA/DC sent you (or don't, it won't matter) but give him a call, talk to him about your needs as a heads up and then be ready when his dashboard opens... (see a forthcoming post about that). Also, you'll see in a moment why I say Criswell but for now just know they took the MSRP pledge and the No Unexpected Option Guarantee, so you can't go wrong with Criswell!
I've contacted at some level all 40 or so LEAF-Certified Dealerships in the D.C. Area and hope to put up more Meet Your Dealership posts in the http://aecn.timehorse.com/ blog soon. For now, watch that space for some very important and exciting news!
