When evaluating used Zotye vehicles, buyers must focus on engine health, transmission stability, and electronic system integrity. Specifically, check for the Mitsubishi-sourced engines often found in older models (like the T600) or Zotye’s self-developed units in newer series. Ensure the CVT or Dual-Clutch Transmission (DCT) shifts smoothly without hesitation. Additionally, verify the mileage authenticity via digital odometer checks and inspect the chassis for rust or structural repairs, as these significantly impact the vehicle's resale value and safety.
