Same happened to me, first I taught it was dirt but realized somebody trying to parallel park beside the Supra , scraped the front of the bumper, like claw marks on her.
Luckily for me , my friend is a detailer, once he seen it , he was nearly sure he could buff it out; and he did it was more paint transfer off the other car than panel damage!
One of the ladies in a Silver Corolla parks there sometimes, her car has a dent on every panel, even the roof FFS! I have seen her trying to park before, very nervous driver, buried into the front windscreen but you cant accuse her as I cannot prove it!
Glad you got some good news, Gabriella ! It is the downside to having a nice car!
