The bottom line
High repaint rates plus extra structural repairs mean you should treat a shiny Mustang as a patched car until proven otherwise, so get the structure checked first. Then go straight to the engine bay and underside because oil leaks show up on 57 percent of them and fuel-trim issues follow, so look for seepage, run a scan, and inspect the tires. Walk away if you find leaks together with structural work. Only a dry engine and an unrepaired frame are worth negotiating.
