@Lindenwood Ahhh...I feel for you. Our M3P is shared and living in a city we street park all the time. Let's just say it has a good side and a bad side for photographs.
I even contributed one of the curb marks.
I decided to make mental peace with curbing before we even picked up the car, because with our often rushed family / child activity schedules, it's bound to happen.
I was also the first one to cut over a curb by mistake! But with 18s no scratches or bending or anything from that...was just at like 2mph pulling out of a parking spot.
Climbed right over the curb without issue, rim never touched it. Later my wife cut a curb making a fast right turn but luckily it had a crosswalk cutout. I don't even want to know what's happened when I'm not in the car.
