There is a Ryder in Long Island City, Queens that has them for rent. Depending o your business or personal accounts it starts at $100/day plus miles depending on your deal, from .17-.85/mile.
Hatzlacha Rabbah & I also believe all Ryder locations do carry Sprinters. Whether they are rented out all the time you must call to find out. They are also Frieghtliner Dodge I believe NOT Mercedes.
