At Franconia-Springfield Metro station garage, just 3 stops from DCA. A few dollars metro ride and $5 parking fee verses an expensive airport drop off. Avoid the parking fee with a weekend pickup or M-F before 9.
Great little car for commuting around the DC area. Easy on fuel but still has enough power to get into traffic with ease, 4 speed automatic transmission, cruise control, AM/FM radio with audio input jack and usb for powering accessories.
