I would...that's such a dick move to f*ck with someones car...if your going to confront them...just do it face to face...don't be a woman and damage the property...and if they did it to you, take it to the cops. Also, that is why fluids is the last thing I do...going S/C oil, to engine oil, to the coolant.

As for the car...sorry Jess, sounds like you got hosed.
