I have the same specs you Midnight air M2 except mine is a 13 inch lol, but I've not had a MacBook for a good while , I think it was the 13inch 2016 MacBook Pro no Touch Bar that was in space gray and that had these marks around the usb c port.Some readers have pointed out scratching around the usb-c ports on midnight, but my space gray work laptop also has these, it seems like normal wear and tear that happens with all colors just doesn’t show on silver.
