My e46 328ci came with some rear arch rust (replaced panel) as well as slight bubbling on a front arch. So it went into the body shop and I parted with £400 cash for these to be sorted as well as the front bumper resprayed.
Now about 5 months down the line the rear rust is breaking through and the front arch has bubbled up even worse!!
I know it will come back but this soon??
