UPS hit and run.

[cheeks]

Maybe it would be wise to notify your insurance ? Just to lt them know it advance. It's not your fault - your rates won't go up. But insurance companies don't like it, if they get notified by the other party first (other insurance company).

Also as in any other accident or hit and run you should have had the police there to make a police report. Don't get to involved on the trust area. . .been there tried that.
Any driver with a prior might have been afraid to report the damage. UPS does not believe in accidents. . .
