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.

Parts availability depends on the brand's official presence in your market, but even unsupported brands can be maintained through direct ordering. Check three channels first: the brand's official dealer network (if any), third-party importers who specialize in Chinese auto parts, and generic equivalents. For wear items like brake pads, filters, and wipers, aftermarket suppliers usually stock cross-references by VIN. For model-specific parts — headlights, sensors, control modules — order directly from China. Ask your exporter for the parts catalog by VIN, confirm OEM part numbers, and compare prices. A turbocharger that costs $900 from a local dealer often ships from China for $350 plus $80 freight. Practical tips: bundle multiple parts into one shipment to amortize freight; ask for DDP (delivered duty paid) pricing so customs clearance is handled; and always verify part numbers against your VIN before paying, as Chinese models have running changes mid-year. Keep a small stock of common wear parts — oil filters, air filters, spark plugs — to avoid a 4-6 week wait for routine maintenance.

The technician will check the production date codes and brand logos in the lower left corner of all the car's glass (including the windshield, four doors, and rear window) to see if they match the vehicle's factory date on the nameplate. If any glass is found to have a date later than the vehicle's production date, it will be recorded as evidence of a "previous damage replacement."
