They won’t go back on the assembly line. Likely what will happen is they will go to the local dealership or body shop and get fixed. A rebuilt tile is possible and if so will sell at a discount. Body shop will simply bill the insurance for repairs.
I know it will not go back through the assembly line, and I’m guessing on the body shop, but the only place at the plant that could do the repairs is so swamped with fixing trucks coming off the line there is no place to insert then in the process. Also, they look to already be sold to a dealership as they have had the dealer prep work done.
