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.

Most exporters offer a limited warranty of 30 to 90 days covering major mechanical failures (engine, gearbox, electric motor), but only if you can prove the fault existed before shipment. Cosmetic issues, wear-and-tear parts (brakes, tires, clutch) and damage caused by improper local maintenance are almost always excluded. What is realistic to claim: · Engine or transmission failure confirmed by a licensed workshop within the warranty window, with a diagnostic report. · Undeclared accident or flood damage discovered after arrival (strongest case, keep the inspection report and photos). How to protect yourself: 1. Get the warranty terms written into the contract, including claim procedure and response time. 2. Have the car inspected locally immediately upon arrival and keep all records. 3. Communicate claims in writing (email) with photos and reports attached. Treat the warranty as a backup, not the main protection. A thorough pre-shipment third-party inspection matters far more than a paper warranty.

Remote mechanical assessment relies on documented evidence: 1. Cold-start video: Ask for a video of the engine starting from cold — listen for rattles, watch for smoke (blue = oil burning, white = possible head gasket issue). 2. OBD scan: A full diagnostic scan reveals fault codes in the engine, gearbox, and electronics. Request the raw scan report, not a screenshot summary. 3. Service records: Cross-check mileage against maintenance records and inspection stickers; consistent records indicate a cared-for car. 4. Fluid check: Photos of the oil dipstick and coolant color tell a lot — milky oil or rusty coolant are red flags. 5. Test drive video: A short drive video shows gear shifts, braking, and steering behavior. Combine these with the pre-shipment inspection report. A seller who refuses to provide cold-start video or OBD data is a warning sign.
