RoRo (roll-on/roll-off) is cheaper and faster for a single car—you drive it onto the vessel and it is secured on the car deck. Container shipping costs more but offers better protection from weather, salt air, and handling damage, and allows you to load spare parts inside the car. Marine insurance is essential either way. Standard cover protects total loss and major damage, but read the exclusions: many policies do not cover pre-existing mechanical faults, cosmetic scratches below a deductible, or damage caused by improper securing (lashings). Ask for ICC(A) or All Risks coverage rather than basic total-loss-only policies. Practical tips: 1. Photograph and video the car thoroughly at loading, with the VIN visible 2. Note existing scratches on the bill of lading 3. Inspect immediately at destination—claims windows are often 3-7 days 4. For EVs, declare the battery; some insurers charge a supplement or exclude battery damage altogether

Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

State of Health (SOH) tells you how much of the original battery capacity remains. Here's how to use it. Reading the report: SOH is usually shown as a percentage of original capacity. A car at 90% SOH retains roughly 90% of its original range. Also check for cell imbalance (voltage spread between modules)—a low SOH with balanced cells is often fine, but high imbalance causes sudden range drops and charging problems. Acceptable thresholds: for a car under 3 years old, expect 90%+ SOH. For 3-5 years, 85-90% is normal. Below 80% SOH, the battery may soon need replacement—replacement costs can exceed the car's value, so negotiate hard or walk away. How to verify: don't trust a screenshot. Ask for a live screen recording of the diagnostic app (like the brand's official tool) starting from the car's VIN page. Cross-check the fast-charging curve: a healthy battery charges at near-peak rate up to 60-70%; a degraded one tapers early. Finally, remember that hot climates degrade batteries faster—if the car spent its life in southern China, scrutinize SOH more carefully.
