Ford Mustang GT S197: old-school muscle, modern enough to live with
The S197 mixes simple rear-wheel-drive fun with one of the biggest engine upgrades in Mustang history. Here is where the generations split—and why the 2013–2014 GT is such a sweet spot.

The S197 Mustang still feels like a traditional muscle car: a long hood, a naturally aspirated V8 and a rear axle that can make a rough road feel busy. That simplicity is also part of the appeal. It sounds special at normal speeds, parts are everywhere and you do not need exotic-car money to maintain one.
There are really two stories here. The 2005–2010 GT uses the 4.6-liter three-valve V8, while the 2011 model introduced the 5.0-liter Coyote. If performance is the priority, the later car is the one most shoppers mean when they say S197 GT.
What changed across the generation?
The 2010 facelift sharpened the body, but the major mechanical leap came in 2011. The new 5.0 produced 412 horsepower at launch, then rose to 420 horsepower for 2013. Those final two years also received a more dramatic front end, LED tail lamps and available Track Apps.
A GT Premium mainly improves the cabin with leather and comfort features. The GT/CS is an appearance-focused California Special package. Brembo-equipped cars are attractive if you value stronger brakes, but condition matters more than a badge on a heavily modified example.
What should you inspect?
Start with the modification list. Intakes and axle-back exhausts are common and usually harmless, but an unknown tune, aggressive suspension setup or evidence of repeated drag-strip launches deserves more scrutiny.
- Listen for transmission whine, grinding or reluctant shifts on manual cars.
- Check the rear axle and differential area for leaks, clunks or wheel-hop-related abuse.
- Confirm that cooling, air-conditioning and every dashboard display work normally.
- Look for uneven tire wear and mismatched tires—both can reveal a cheap build or alignment issue.
Who is it for?
Choose the Mustang if you want V8 character, easy parts access and a car that can commute during the week without losing its personality. The solid rear axle is less polished than the independent setups in some rivals, but it also gives the S197 the straightforward feel many owners love.
RevFinder verdict
RevFinder pick: a stock or lightly modified 2013–2014 GT Premium with documented maintenance. An automatic is a perfectly reasonable street-car choice; buy the cleanest history, not the loudest exhaust.
