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.

Water damage is one of the most common hidden problems in used cars, and it often escapes basic photo reviews. During a live video inspection, ask the inspector to check these specific points: 1. Smell test: A musty or moldy odor inside the cabin is the first red flag. Have them open all doors, run the AC briefly, and smell the air from the vents—musty AC often indicates water in the HVAC system. 2. Under the carpets: Lift the floor mats and look for water lines, rust stains, or dampness on the carpet backing and the metal floor underneath. Sediment or silt residue is a giveaway. 3. Seat rails and bolts: Pull the seats fully forward and backward. Rust on seat rails or fresh-looking bolts suggests the seats were removed for cleaning after flooding. 4. Trunk area: Check the spare tire well and under the trunk carpet for standing water marks or rust. 5. Electronics: Test every window, seat adjustment, and the infotainment screen—water-damaged electronics behave erratically. Also request a scan report: flood cars often store history codes for multiple control modules that failed simultaneously. Cross-check the car's origin; vehicles from flood-prone southern regions deserve extra scrutiny.

It depends on the brand and model, so verify before you buy. Three things to check. First, connectivity: many Chinese EVs use embedded SIMs tied to Chinese carriers. Abroad, remote app control, live navigation and some cloud services may stop working unless the car can switch to a local SIM or the brand operates servers in your region. Second, language and navigation: ask the exporter to show the system menu in English or your language, and confirm the maps can be switched to your region — some head units carry China-only map data. Third, charging: verify the charge port standard (GB/T, CCS or Type 2) and whether the onboard AC charger accepts your local grid voltage and frequency. Also ask about OTA updates: official overseas models usually receive them; grey-import cars often do not. Get these answers in writing from the seller, and test the connected features over a video call before shipping.
