DIRECT ANSWER
Make the decision from one identified vehicle.
Traction-battery state does not establish healthy low-voltage support. Long storage, repeated short demonstrations and accessories can weaken module wake-up and loading reliability while the vehicle still appears new or low mileage.
Keep the market context attached to every claim. Production date, propulsion, configuration and destination can change what an advertised number means. Mark facts as verified, seller-stated or still open; official model literature never proves the equipment or condition of a particular used vehicle.
CONNECTED DECISIONS
Use the evidence in its wider route
- Separate connected-service issues through the software and account checks.
- Include auxiliary support in the destination support plan.
EVIDENCE FILE
Records that change the answer
Start with production and storage timeline and link it to the VIN before accepting translated trim names or catalogue photographs. Add auxiliary-battery identity and test method so condition or equipment claims can be checked against the actual car. The remaining records establish how the vehicle operates, how it has been treated and whether the proposed route is credible.
- production and storage timeline
- auxiliary-battery identity and test method
- wake-up and shutdown diagnostic record
- accessory, tracker and modification inventory
- carrier handover and arrival plan
Give each record a capture date and a defined scope. Diagnostics taken before repair, charging evidence from another car or freight priced to a different port cannot support the present decision. A replacement VIN starts a new evidence chain rather than inheriting the first candidate's file.
DECISION TEST
Test the route, not the brochure
Compare a stored unregistered vehicle that needs repeated external support with a used candidate showing stable normal-rest voltage and module communication. Resolve reserve and parasitic-load evidence before assigning value to the new label.
Prefer the vehicle whose identity and operating limits can be demonstrated with current records. Put a cost or condition beside each unresolved item instead of concealing it in a general assurance.
Inspection scope should follow the decision. For this route, check build a dated production, storage, movement and charging timeline, then identify and test the correct auxiliary battery after normal rest. Continue with preserve warning and communication history before clearing and record check accessory loads, shutdown stability and arrival recommissioning. Measurements, photographs, diagnostics and test conditions are more transferable than labels such as “excellent,” “full option” or “export ready.”
Risk boundary
Jump-start success or a recently charged battery proves only temporary operation. It can hide lost capacity, accessory draw or a module that fails to enter the expected low-power state.
A known shortcoming can be accepted when its consequence, remedy and price are visible. An untested claim is different: keep it open in the quotation and link payment timing to the check that can close it.
DESTINATION CONTROL
Carry the same facts through export
Follow current carrier instructions for DM-i fuel and battery or EV state, document auxiliary condition at handover, remove prohibited devices and define the first safe wake-up and warning check at destination.
Before collection, read vehicle identity, propulsion, value and trading parties across the commercial and shipping drafts. Destination acceptance and carrier acceptance must both be checked; customs release alone is not proof that road registration will follow.
State where the cost calculation ends and when it was prepared. Include vehicle preparation, inland logistics, freight, insurance, duties, taxes, compliance, storage, destination transport and initial service as applicable, while keeping unconfirmed charges visibly contingent.
BUYER QUESTIONS
Questions to settle before payment
Can a jump start prove 12V health?
No. It shows only that external support restored operation.
Does low mileage remove storage risk?
No. Batteries, tyres, brakes, fluids and seals age with time.
What must be repeated after replacement?
Charging support, warnings, communication, wake-up and shutdown behavior.
PRIMARY REFERENCES
Verify the current market version
BYD lists the current China-market vehicle through separate official Sealion 06 EV and Sealion 06 DM-i pages. Official pages describe the model family; the candidate still needs VIN-linked verification, and destination rules require separate confirmation.
