Might be worth talking to some of your nearby BMW dealers after-sales people. It may be a UK thing, but my local dealer offers a flat-rate package of £80 ($102 USD)/panel repair for minor scratches and dents. In short succession, I got two minor dents parking at the gym, and a set of scratches I'm sure were from a supermarket trolley, across door and rear quarter. Local dealer repaired both for 2x £80+tax versus £3-400 ($382-$510) from an independent repairer/detailer.

Talking to the BMW garage, they said the price was competitive to bring people into the showroom (long service intervals mean fewer people coming into the franchise) and get customers used to using the dealer's paint shop for more serious repairs. Also to attract customers 35 miles away in S. London using much cheaper day rates than in the capital.
