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.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.

Two main shipping methods are used for used cars from China: 1) Container shipping: the car is loaded into a 20ft or 40ft container. Safer, protects from weather and damage, and allows personal items inside the car. Slightly more expensive. 2) RoRo (roll-on/roll-off): the car is driven onto the ship. Cheaper for single units, but no protection and no personal belongings allowed. Typical transit times from major Chinese ports (Shanghai, Guangzhou, Shenzhen, Qingdao): - Middle East: 12-20 days - Europe: 25-40 days - East/West Africa: 30-45 days - South America: 35-50 days - Southeast Asia: 5-12 days Add 5-10 days on each side for port handling, customs, and inland delivery. Peak season (before Chinese New Year and summer) can add delays, so book space 2-3 weeks ahead.
