You could definitely take the insurance check, spend $350 to put a door on yourself, and pocket the remaining cash.

Otherwise, if it isn't costing you a dime, get a new door on and have the body shop blend the paint. I don't think it will be a $2150 repair, but closer to $3k. My parents had to get a front quarter and driver's door replaced on their X5. It ended up over $4k using new parts.
