The bottom line
When you're standing in front of a used Mustang, treat the body and the engine as the two make-or-break items. Nearly every one has at least one repainted panel and structural repairs turn up regularly, so get underneath and look for fresh welds or mismatched paint before you fall in love with the looks. Then check for oil leaks—they show up on 56 percent of these cars—and scan for fuel-trim problems. Worn tires are another common hit. If you spot leaks plus any crash evidence, walk or slash the price hard; only a leak-free engine and original panels are worth full money.
