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.

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.

The industry-standard structure protects both sides. Pay 20-30% deposit after signing the contract and verifying the exporter's license—never more. The balance is paid only after your independent inspection report confirms the car matches the contract, ideally against a copy of the bill of lading so the exporter can't ship a different vehicle. For extra protection, tie payments to milestones: deposit on contract, second tranche after inspection passes, final payment when shipping documents are released. Some buyers use escrow services or trade assurance platforms for the first transaction with a new supplier; fees run 1-3% but are worth it for large amounts. Always pay to a corporate bank account matching the exporter's registered name. Keep every agreement in the written contract—verbal promises like 'we'll fix that before shipping' are unenforceable. If an exporter demands 50%+ upfront or full payment before inspection, walk away; that structure leaves you with no leverage.
