What owners say
S3
Overall
Overall sentiment is positive, with the S3 consistently praised as an excellent all-around daily driver that blends performance, luxury, and practicality. Owners frequently describe it as "stupid fast," a "rocket," and a "blast" to drive, with the Quattro all-wheel drive system inspiring confidence. The interior is widely regarded as high quality, especially when compared to platform-sharing competitors like the Volkswagen Golf.
Best version to buy
Insufficient owner data available to declare a consensus "best" model year or trim. Discussions indicate a preference for the 7-speed DSG (DQ381) transmission found in 2018+ models over the 6-speed (DQ250) for its smoothness and increased torque capacity, which is beneficial for tuning.
Known issues
- ⚠High maintenance and repair costs: very frequent mentions of expensive routine services (e.g., $750 USD for 20k/40k mile service) and costly repairs for common failures.
Mustang
Overall

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.
