I have a 03 Xterra and bumper is bent. The bumper cover, the outer plastic is fine, but it's bent down, I hit a car, rear-ended. Macco wants to replace the brackets and underside bumper with a cost of $450! If I take off the bumper myself, what will I probably be doing? What's underneath that is bent, can anyone tell me what I'll probably be fixing or replacing? I'll post a picture.
