Correct fuel cap with star

[1132021benz]

Driving along today on the highway and heard a small metallic noise.  Looked back, and saw something shiny and silver bouncing behind me.  You guessed it.  My original gas cap.  Yup.  Anyone have a good one with keys that I might persuade them to part with?

Thank you!

Go right back and look for it.  Can't be that hard to find again.
They are big $$$ if you find the correct one with the star and keys.
