The bottom line
These Mustangs carry a heavy accident shadow—structural repairs hit far above the norm and nearly every example has resprayed panels—so the shiny exterior often masks real chassis damage. Layer on the engine’s dominant oil leaks and out-of-range fuel trims and you have cars that can look sharp yet already be leaking and running rich or lean. On any candidate, put it on a lift first and hunt frame welds plus fresh seepage at the engine and drivetrain; tires are the next quick tell. Walk if the structure is touched or leaks are active, otherwise use those findings to cut the price hard—history and current condition matter more than the badge.
