What to pay for a used BYD Sealion 6

The Sealion 6 PHEV only arrived in Australia in late 2023 so used supply is still emerging. Early examples are appearing from fleet and demonstrator disposals at $36,000–$42,000 — representing genuine value against a new equivalent at $45,000+. Negotiate firmly on demonstrator examples where dealer motivation to move stock is high.

CarBuyAgent take

Strong buy — best PHEV value in class

The Sealion 6 PHEV is the most compelling new-to-used-market buy in the EV/PHEV segment right now. It bridges the gap between full EV running costs (for daily driving) and the confidence of a petrol backup — which remains the single biggest objection to used EV purchases. Fleet and demonstrator disposals in 2024–2025 created a window of genuine value that won't last. A 2023 Premium PHEV at $38,000–$42,000 with under 20,000km is an outstanding buy.

Known issues on the BYD Sealion 6

Very new to market so long-term data is limited. Early software versions had minor infotainment issues — confirm software is current. PHEV system adds complexity vs pure BEV — ensure both petrol and electric systems are checked. AdBlue not required on this engine.

CarBuyAgent EV pre-purchase check: We require a current battery SoH report from every seller before presenting an EV to a client. Vehicles below 85% SoH are not shortlisted. For the full concierge service, we verify all EV-specific requirements as a condition of the engagement — before you commit a single dollar.
