The short answer
The Ford Mustang offers power, while the Kia Stinger excels at fuel economy instead. Choose the Ford Mustang if you prioritize power in daily driving, or the Kia Stinger if fuel economy matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is highly fragmented and generation-dependent. Long-term owner reports for older generations (e.g., SN95/New Edge, S197) often express strong satisfaction with reliability, simplicity, and the ownership experience, with some owners reporting trouble-free operation well past 100,000 miles. For the S550 generation (2015-2023), feedback is mixed.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Isolated positive remarks exist for the S550 Mach 1 for its balance of performance and reliability compared to the GT350, and for the 2013+ S197 GT500 for its historical impact.
