2005–2014 Ford Mustang Review: Should You Buy It?

4 min read

Also worth reading: 2015–2023 Ford Mustang Buying Guide, Ford Mustang Buying Guide and Ford Reliability Guide.

The 2005–2014 Ford Mustang covers the 5th gen (S197) generation from start to finish. Mechanically these years are the same car — same platform, same engine family, same failure points — so shop the individual car's condition and service history rather than chasing a specific model year. 2011+ 5.0L Coyote GT is the enthusiast pick. Live-axle cars are cheap and easy to own.

Model-year changes

What's New in the 2005–2014 Mustang?

This generation launched in 2005: Retro-styled S197 platform, live rear axle, wide engine lineup. Mid-cycle updates landed in 2010, 2013, so later cars in the span pick up interior and tech revisions. Powertrain and core hardware carry over across the span, which is exactly why we cover the whole generation on one page instead of splitting near-identical years apart.

Reliability

How Reliable Is the 2005–2014 Mustang?

Across 2005–2014, reliability tracks the generation as a whole rather than any one model year. Early-build cars (2005–2006) carry the usual first-run risk, and late-run cars have had years of TSB and running fixes applied. The issues that actually decide whether a car is worth buying: Coyote 5.0L rear main seal leaks (early); 4.6L 3V spark plug break issues; Axle hop under aggressive launches.
