Should a 4-5 inch scrape on a Jeep cost $750 to fix?

What is your question?

I got into an accident yesterday where I bumped into a Jeep's front bumper. So, I left a note for the owner with my contact info. Well, today I got a call from an auto body telling me that it would cost about $750 to repair because they will have to remove the bumper, repaint it, etc. I don't know much about repair costs... Am I being ripped off here?
