Re: Scraped up the back bumper
This is what you pay comprehensive for on your insurance. Someone hit my back bumper less than a week after I bought it. I called in the claim. My deductible is $200. Total bill was near $1,000.
They had to replace the entire rubberized bumper cover, so that's why I expect it was that much. If you are just repairing scratches, it's going to be MUCH less. Probably lower than your deductible.
As stated get a professional estimate or three and then you will know if it's worth making a claim for.
Cheers!
