Riverdale is a quasi-suburban neighborhood in NYC, just north of where the Harlem River joins the Hudson River (aka Spuyten Duyvil). Some apartment buildings have garages. You could keep a car on the street in some parts of Riverdale if you don't mind the hassle of moving it all the time due to street sweeping/plowing etc. Wikipedia has a decent write up http://en.wikipedia.org/wiki/Riverdale,_Bronx
