What owners say
Corvette
Overall
Owner sentiment is mixed and heavily dependent on generation and specific model. The C6 generation (2005-2013) is frequently discussed, with owners appreciating its performance value and LS-based engine reliability, but reporting recurrent electrical and fuel system issues, particularly in higher-mileage examples. The C7 generation (2014-2019) is noted for its performance capabilities, though isolated reports mention specific mechanical problems requiring significant repair.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. The C6 Z06 and Grand Sport are mentioned positively for their performance.
Known issues
- ⚠Electrical system malfunctions (C6): erratic gauge behavior (fuel, battery), RPM fluctuation, intermittent power loss. Frequency: recurrent.
- ⚠Fuel system leaks (C6, C4): strong fuel smell, particularly when tank is full; attributed to cracked plastic fittings on top of the fuel tank. Frequency: recurrent.
- ⚠Slow or problematic startup (C7): sputtering during hot starts, remote start failures, potentially linked to a Fuel Pump Control Module. Frequency: isolated.
911
Overall
Sentiment is deeply polarized and varies significantly by generation and model.

The 911 is often cited as a benchmark for driver engagement and is recognized as a highly satisfying vehicle to own.
Best version to buy
997.2 Generation: Specifically praised as the "absolute best modern 911" for combining hydraulic steering, a manual transmission, and a modern enough interior. The 997.1 Turbo is also highlighted as a desirable, proven performance variant with a durable engine and dry-sump oiling.
Known issues
- ⚠Extremely high maintenance and repair costs: Major engine or transmission failure can cost more than the car's value, and parts are exceptionally expensive. Frequency: very frequent.
- ⚠Turbo lag in modern turbocharged engines (991.2, 992): Noted as a significant dynamic flaw, with criticism that reviewers downplay its presence. Frequency: recurrent.
- ⚠Interior material quality and durability: Hard plastics, manual seats in base models, and specific issues like peeling door cards on 991 models left in the sun. Frequency: recurrent.
