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.

A proper pre-shipment inspection is more than photos — it is a documented technical examination covering four areas. 1. Structure: paint thickness readings across the body, weld inspection of pillars and chassis rails, rust assessment underneath. 2. Mechanical: engine compression or at least a cold-start video, transmission shifts through all gears, suspension noise test on uneven roads, brake pad and disc thickness measurements. 3. Electronics: full OBD diagnostic scan with printed fault codes, all lights, windows, AC, infotainment, and driver-assistance functions tested. 4. Documentation: VIN and engine number physically matched to the registration certificate, photos of the certificate itself. Insist on a written report with photos, measured values, and a clear pass/fail conclusion per section. Make final payment conditional on this report, not on the seller's word or showroom-condition photos.

Unauthorized personnel are prohibited from entering and taking photos inside the roll-on/roll-off ship, but we will provide photos of the vehicles parked in the loading area with the ship in the background. The bill of lading marked "Shipped on board" with the date is the most essential legal proof of loading.
