I definitely have not done this and am totally speaking hypothetically here.

If you did not file a police report or have insurance involved you may be better off just having it fixed without reporting anything.

If all you need is a new bumper it will probably come out to less than $1,000. Take a look at your deductible vs a couple estimates and see if it is even worth it to get insurance involved and sometimes body shops will give you a discount if they don't have to do any insurance reporting....

If insurance/police report is already involved then like others said there is no harm in seeing if you can get diminished value
