The bottom line
A Mustang that looks sharp on the lot still carries elevated odds of prior structural work and fresh paint, so treat every panel gap and underbody seam as suspect. Pair that with oil leaks showing up on 57 percent of them and fuel-trim problems close behind, and the smart move is to budget for a lift inspection focused first on frame rails and engine seepage. If either is present, negotiate hard or walk—these cars punish buyers who skip the deep check.
