Damage to back left, no idea when or how it happened.
First pic is damage I just noticed today. No idea when it happened or how it happened. 2nd photo is other side showing what it should look like.
I’m only one who drives it, so it had to be someone hitting me when I was parked somewhere and not leaving a note or anything.
That white piece being so bent inward makes me think something thin smashed into it bc theres no damage to the light above it. Bumper below it does have a crack, so maybe another cars bumper just hit with enough force to crack bumper and push that piece inward?
Any sleuths have a better reasoning for what might have happened here?
FWIW, I can access the bent white part from underneath the car but I imagine it would be hard for me to bend it back into place like on the other side.
