A complete service history tells you more about a car than its mileage. In China, most maintenance is done at authorized (4S) dealers, and each visit is recorded in the brand's national database. First, ask the seller for the service booklet and maintenance invoices, then have your inspection agent call the brand's 4S network with the VIN to pull the full service record. This shows oil changes, major repairs, recall work and accident-related repairs. Second, check that the mileage recorded at each service visit increases logically. A gap between the database mileage and the dashboard reading is a red flag. Third, ask for the annual inspection (nianjian) records, which are mandatory in China and show whether the car passed emissions and safety checks on time. If the seller claims a full service history but the database shows no records, assume the car was maintained at small independent shops or neglected. Adjust your offer accordingly — plenty of used cars in China have documented histories.

Mainstream Chinese automakers rarely publish official English versions of their underlying circuit diagrams. We can provide some models' original Chinese technical documents (PDF) for B2B clients, which you will need to translate for your local mechanics using translation software.

If your market is in extremely cold regions (like Russia or Northern Europe), we strongly recommend purchasing ternary lithium (NMC) models equipped with heat pump air conditioning. The range achievement rate of used LFP batteries typically plummets at minus 15 degrees, and we will alert you accordingly.
