I just wanted to post a follow-up on this saga, since it was requested.
Car is back...I kept telling the paint and body guy "Take the time you need...don't rush." His receptionist thought I was a nut.
He fixed the scraped/bashed area...several other minor scuffs nearby, an older keymark, a tiny bit (less than 1 sq cm) rust on the edge of the gas filler cap, and cleaned up the TINY scratch on the alloy rims. We had only negotiated a price for the affected area, which is all he asked me to pay. The rest came just for leaving the car there and giving him time to play. It looks great, by the way...and I have no paint imperfections on the car at all, that I can locate.
Thanks for all the advice, now on to the new member of the family...the 300D that I get to pick up in about 25 minutes.
