Plan for roughly 25-40% on top of the vehicle price. The main items are: 1. Pre-purchase: deposit (10-30%), third-party inspection fee (100-300 USD). 2. In China: inland trucking to the port, export declaration fees. 3. Shipping: ocean freight (container 20ft usually 1,500-4,000 USD depending on destination), marine insurance (about 0.3-0.5% of car value). 4. In your country: customs duty, VAT/GST, port handling and storage, customs broker, quarantine or pre-shipment inspection if required, registration and plates. Always ask the exporter for an itemized landed-cost estimate for your specific port before paying the deposit, and confirm which Incoterm the quote is based on (FOB, CIF or DDP makes a big difference).

A proper inspection relies on equipment, not just eyes. The inspector should use a paint thickness gauge to measure 50-60 points across body panels; original paint is typically 80-150 microns. An OBD diagnostic scanner reads stored and pending fault codes across all control units, and for EVs it also reads battery state of health and charge cycle counts. The car must go on a lift for the underbody check: frame rails, suspension components, oil leaks and accident repair marks are only visible from below. A battery tester checks starting voltage and charging system health, and a tread depth gauge documents tire condition. Ask for the report to include raw readings and dated photos rather than a simple pass/fail summary - that is what makes it verifiable.

It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.
