With early 3-year novated leases finishing up, the second-hand market for 2023–2024 BYD Atto 3, Dolphin, and Seal models is booming! Here is what private buyers and sellers need to know:

On-Road Impressions, Efficiency & Setup Details
- Factory Warranty Transfers 100% Free: Both the remainder of the 6-year / 150,000 km vehicle warranty and the 8-year / 160,000–200,000 km Blade Battery warranty transfer automatically with the VIN.
- Transferring BYD App Ownership: The previous owner simply taps "Unbind Vehicle" in their BYD App (or the new owner uploads their registration transfer paper inside the app) and full remote app access transfers within 24 hours!

Just bought a 2023 Atto 3 Extended with 42,000 km privately—still has 5 years of Blade Battery warranty left and OBD2 showed 96.8% SOH!
