Rented at IAD again this weekend. Friday noon pickup.
EA - a couple of nondescript small cars.
ES - Empty.
Bus driver pointed at the next two aisles over and said "Just take anything from there." It happened to be Premium and Minivan. Both aisles were full of cars...plenty of good selection from both types. We took a Dodge Charger with low miles and Sirius radio. No Maximas though - I was looking for one.
In general, their lot was pretty full of cars in all sizes. They should have had some availability on ES, but we were happy with the Charger.
