Geez that thing is bad. Mustangs are pretty cheap and available, I would consider starting with a better body. After sheet metal work ,panel costs, labor, some things aren't worth saving. Can't believe some people. You can't completely blame the shop tho,the customer may have insisted on having it fixed quick and cheap. When the economy was even worse then now I've seen some shady things done at a few places and called them out on it. People get desperate and don't want to loose the money from the customer and work like this becomes the norm.
