I’ve heard from various sources that the business of bodywork repairs on cars, between the docks and the dealers, is very well organised and quite busy. Surprised that your dealer did not use the mileage reset option but, as said in the post on delivery miles, that is limited, so was possibly not available. I’d say forget it all and enjoy the car - they’re all only new for a very brief time anyway, so best to get it christened early and move on!
