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.

Our bulk discounts are not simply calculated by the number of units, but by shipping batches. Typically, consolidating enough for a 40-foot container (which can hold 2-3 vehicles, depending on size) can waive some logistics fees; purchasing more than 5 units at once triggers tiered discounts.

We will provide extremely accurate production year, first registration date, and Chinese emission standards (e.g., National VI). However, the final responsibility for confirming whether this data complies with the importing country's regulations lies with the buyer, and you need to submit it to the local customs for verification before placing an order.
