Should You Buy the 2021 Nissan Sentra?

The 2021 Nissan Sentra offers a comfortable ride and good fuel economy, but its Achilles' heel remains the Continuously Variable Transmission (CVT), which introduces a significant long-term reliability risk. While generally a decent daily driver, I advise proceeding with caution due to the potential for expensive transmission failures down the line.
