A solid contract is your main protection in a cross-border deal. It should specify: 1. Vehicle identification: VIN, year, mileage, trim level, and photos of the actual car appended as an annex — not just「a 2021 Toyota」. 2. Condition guarantees: no accident, no flood or fire damage, no structural repairs, supported by a third-party inspection report referenced in the contract. 3. Price and Incoterm: total amount, currency, the named port, and whether freight and insurance are included. 4. Payment schedule: e.g., 20–30% deposit after contract signing, balance against copy of the Bill of Lading. Avoid 100% upfront. Use T/T to the company's corporate bank account only — never a personal account. 5. Timeline: inspection date, estimated loading date, and latest shipment date, with remedies if delayed. 6. Dispute clause: governing law and arbitration (CIETAC or your local chamber) rather than foreign court litigation. Ask for the contract in English (or bilingual) with the supplier's company chop. A company that refuses a written contract or pushes for full prepayment is a red flag.

Ask for a specific set of photos and video taken with the car on a lift — generic walk-around videos will not show what matters. Request close-ups of: the sills (rocker panels) on both sides, front and rear subframes, suspension mounting points, brake lines, and the floor pan under the carpets. Surface rust on bolts is normal; bubbling paint, flaking metal or fresh undercoat sprayed over corrosion are warning signs. Also check for flood damage, a common hidden problem: look at the spare wheel well for water marks or mud, pull up the trunk carpet, and check the seat rails and seat belt buckles for rust or silt. A musty smell reported by the inspector is a red flag. A trustworthy exporter will provide a lift inspection report listing measured paint thickness on structural areas. If they refuse to put the car on a lift, treat that as an answer in itself.

It must be stated objectively: used cars in China are produced according to national standards (GB) and have not been originally certified by Saudi SASO or GSO of Gulf countries. Buyers must find a local agent with customs clearance capabilities to complete the clearance through exemption documents or compliant modifications after arrival (such as wrapping or adding specific alarms).
