I strongly recommend Beyer's Subaru in Alexandria, VA - I worked with Matt N. there to order a 2011 WRX premium white 5-door with plenty of options (shift, exhaust, . . .), out the door for about $30K. He had the car for me in about 6 weeks.
Shockingly easy and great car buying experience - Matt is very happy to negotiate via e-mail and there were no surprises when I picked up the car.
