I hate people!!! Whats involved in fixing this?

[dandg]

Today I looked at my car and noticed that on the driver side of the rear bumper within a 1 foot x 1 foot area is completely scraped up, as if a car was pulling in or out of a parking space and grinded against the side of my car. It had to have happened within the last 2 days.

I would try to take a picture but don't know how well it will show up, it's pretty noticeable in the light. The majority it is about 8 or 9 long inches of many light scratches close together that may be able to be buffed out with a lot of work. Then there is a quarter sized piece of paint that completely chipped off and a 6 inch deep gash which took all the paint off. Also took a large portion of the paint off the splash guard. All of this damage is contained within a 1ftx1ft area and only on the rear bumper panel.

Pisses me off so much how someone could do that to someone elses property and just take off, now I'm stuck paying for it. I've taken very well care of my Z within the 2 years I've owned it. I'd love to confront or catch whoever did this in the act...

But anway, does anyone know what it sounds like will be involved in fixing this? Am I going to have to replace the entire bumper?
