Does the market discount it? In our listings a 2005 Mustang asks a median $7,000, against $6,000 for a 2006, the next model year: 17% more, so the price shows no discount for its complaint record.

Among the 12 Ford Mustang years with enough history, the three to walk away from are 2005, 2012, 2006; the three worth hunting are 2004, 2003, 2017.

ROWS 16·SOURCE NHTSA complaints with incident dates

Basic warranty on this car is 3 years / 36,000 miles. Only 29.8% of reported failures happen inside it — the remaining 70.2% come out of the owner's pocket. Powertrain cover (5 years / 60,000 miles) reaches further, but it only covers the engine and transmission, which account for about 29% of the complaints here.

What actually fails — and at what age

On the Ford Mustang, the early trouble is Power Train — reported at around 3.2 years, so a car still under warranty is the one to check for it. What waits further out is Air Bags at 6.6 years — past every basic warranty, and the bill lands on whoever owns the car then.
