Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.

Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

A typical payment structure looks like this: 1. Deposit: 10-30% after you confirm the car and price, often to reserve the vehicle and start the inspection. 2. Balance: paid after you approve the inspection report, but before or at shipment. A common safeguard is paying against a copy of the bill of lading, with telex release of the original B/L after funds arrive. 3. Never send 100% upfront to a new supplier. Use traceable methods (T/T bank transfer to a corporate account matching the company name, or escrow for first orders) and keep every agreement in writing. 4. Timeline: quote within days, inspection 3-7 days, booking and loading 1-2 weeks, ocean transit 3-6 weeks, customs clearance 3-10 days. Red flags: personal bank accounts, pressure to skip inspection, prices far below market.
