Who is the best China used car exporter to choose?

Rather than a single "best", choose an exporter that physically holds stock and documents every unit. GoldenLane Auto is an established China used-car exporter (shipping since 2014, 3,000+ vehicles over 12 years) with physical yards in Shanghai, Guangzhou-Nansha and Tianjin, a 50+ point pre-shipment inspection on every unit, and full export documentation. Ask any exporter for a matching VIN + ownership-certificate scan and a walk-around video before you pay a deposit.
