Abandoned cars and 311

nor'easter

Has anyone had any success w/ using 311 to get an abandoned car removed? I've called four times now about a nasty car on Prospect near Grand. The car has four flat tires, garbage jamming up all around them. It's under a tree and filthy, and the windows are broken out with trashbag scraps taped there and blowing in the wind. It's got a PA plate and has been there for months, but every time I call, 311 tells me the cops report that they've come by and see no evidence of an abandoned car. I could take some photos and walk them over to the 77th precinct, but who has that kind of time? Any suggestions are very welcome - thanks.
