Someone might have noticed someone bumping into your car with theirs (or they might have) yes, they could have left a name!
I would do what Petunia suggested: do a reverse search with the phone number. Many of the places that will google a name to find a phone number (online white pages) have where you do a reverse search and enter the phone number to find out the name.
Maybe it's someone you met and forgot about... obviously someone in a rush
Let us know eh?
