ur lucky your wheels didnt have curb marks because i can see them using that as an excuse. Either-way, great job.
Also incase others arent as lucky, if your wheels simply show paint/cosmetic damage, a wheel shop usually charges $50-$100 per wheel to refinish them like new... so a new wheel isnt needed unless its damaged structure wise.
glad Nissan covered it. I had a tear on my door panel on the very top and i know it was caused by the window tint guy but played stupid when i went to nissan and they covered it under warranty as defect....BEST PART, I kept the $450 the shop issued me to cover damage
