2015 was a tremendous year for muscle cars. Dodge updated the Charger and Challenger, introduced the Hellcat, and Ford completely redesigned the venerable Mustang. Instead of keeping the pony car retro-syle and old-school cool, Ford modernized the model inside and out. So, should you take advantage of Ford’s efforts and pick up a used S550 generation 2015 Ford Mustang? 

What is the difference between the S550 and S197?

The S550 moniker refers to the sixth generation of the Ford Mustang, which started in 2015. It will continue until its replacement, the S650, hits the streets. The S550 replaced the fifth generation pony car, which Ford named the S197. However, the difference is much more significant than the name alone.

The 2015 Ford Mustang received a complete redesign, ditching the retro-inspired lines for a sharper, more athletic grand tourer-esque platform. Underneath, Ford ditched the live rear axle and incorporated independent rear suspension across the trims for the first time. Also, the marque updated the interior, although it retained a few throwback nods, like the dash brow and analog gauges. Additionally, Ford began fielding a turbocharged four-cylinder trim, the EcoBoost. 

How much is an S550 Mustang?

Depending on the trim, you can snag an S550 generation 2015 Ford Mustang for around $20,000. If you want the gas-saving Ford Mustang EcoBoost, a 50,000-mile example will demand about $20,569. However, if you want the V6 model, you’ll have to spend a little more, with a fair purchase price of $21,013. Still, most customers will opt for the Coyote V8-powered 5.0 GT.

Kelley Blue Book (KBB) states that the 2015 Ford Mustang GT has a fair purchase price of $28,313. That makes it a performance bargain given its horsepower and available six-speed manual transmission. 

How much HP does a 2015 Mustang have?

The 2015 Ford Mustang with the 2.3L turbocharged four-cylinder EcoBoost engine produces a respectable 310 horsepower. While that might not seem like much, it’s more than a V6-powered Dodge Challenger. Furthermore, the 3.7L V6 engine option produces 300 horsepower. However, many S550 pony car fanatics will want the 435-horsepower GT with its 5.0L Coyote V8 engine. 

Is the 2015 Ford Mustang safe?

The 2015 Ford Mustang is a modern muscle car, so safety probably wasn’t at the forefront of the automaker’s concerns. However, the National Highway Traffic Safety Administration (NHTSA) gave the 2015 Ford Mustang a five-star safety rating. Five stars are the highest rating the agency awards, but it doesn’t represent a perfect score. For instance, the S550 Mustang only received four stars in rear-seat side impact testing. 

Which S550 trim should you buy?

If you want a fast, sharp, and better-handling V8 Mustang than previous generations, you’ll have to opt for the 5.0 GT trim. Even better, savvy shoppers who seek a 5.0L GT Premium can enjoy leather seats, a larger infotainment touchscreen, and more handsome wheels. However, you can find an EcoBoost if you want better fuel economy and a smaller price tag for your used S550.
