Vinny from "Jersey Shore" once again put something where it didn't belong -- and this time it cost him.



Vinny's 2011 Mercedes-Benz was towed early Thursday morning in New York City ... so our tow sources say.

Vinny parked his ride in a no-no zone on Wednesday night outside of his buddy's place -- and awoke to discover he was Mercedes-less.

Vinny had to cough up $185 bucks to get the Benz back.
