Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

Air suspension is very delicate. If, after the vehicle has been stationary for about 12 hours, the height on one side of the vehicle drops more than 1.5 cm when measured from the wheel arch to the tire, we will determine that there is a slight air leak in the air spring or distribution valve on that side and warn you of the high subsequent repair costs.

EXW means you pay only for the car at the seller's yard—you handle everything else, including inland transport in China and export clearance, which is impractical from overseas. FOB includes delivery to the port and export customs clearance; you pay for ocean freight and insurance. CIF adds freight and basic insurance to a named destination port. For a first-time buyer, FOB is usually the best balance: the exporter, who knows Chinese logistics, handles the complicated part, while you control the freight booking and can shop rates among forwarders. Watch for exporters quoting unrealistically low FOB prices and making margin on inflated 'shipping services' later. Get a separate freight quote before signing, and compare the exporter's CIF offer against FOB plus your own freight estimate. Ask explicitly whether the price includes inspection, export license fees, and port charges—ambiguity here is the most common source of disputes.
