I drove by the Exxon near Target on Sunset Hills Rd. in Reston and it was $4.099. I know it's only a couple of data points, but the IAD Exxon prices seem reasonable to me. I'm rarely in Centreville or Chantilly so I can't compare against those areas.
My experience is that some of the stations in Centreville/Chantilly are a few pennies less - but hardly worth driving several miles out of the way.
