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.

We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

Our FOB vehicle quotes are typically valid for 72 hours (as domestic retail vehicle sources can be sold at any time); sea freight quotes are valid for 7 to 14 days (depending on shipping line changes). After expiration, prices need to be recalculated based on real-time exchange rates and domestic procurement conditions.
