Please help a tourist - added photos and estimate

Having worked for an insurance company I can tell you that a door ding from a shopping cart routinely cost about $600 to have repaired on a car. In view of the bills I saw for repairs, that amount is not out of line. Also when they paint, they paint out in a larger area than just the damage to blend the paint so that the new and old paint lines are not visible. From the photo the scratch looks superficial and like it could be buffed out??? That would not be near as expensive.
