Curb rash is very easy to repair as long as you can find the right color paint. I do not know the color for the MY rim but someone else likely does. I fixed my M3 rash with about $30 in parts (sandpaper, paint, bondo, tack cloth) and a few hours of my time (mostly spent waiting for paint to dry). I now have everything that I need to fix the next rash (hoping it doesn't happen) so that that one will just cost me time. My repair is not perfect but it is invisible unless you are looking to find it which is good enough for me.
