Do mind that it's often more cost effective to take the train and you have more rental options. I've taken the train from WDC to NYC at times because there were better rental options there when travelling further north.
There is absolutely no way I would take a train into NYC for a cheaper rental option requiring me to drive out of the city. Driving to NYC is already my fastest option but I hate doing it so I basically drive an hour in the wrong direction to catch a train.
