The key to pre-shipment inspection of new cars is to attach the evidence to a specific vehicle and a named person. Confirm VIN and order configuration first, then work through appearance, functions and warning lights and onboard items and documents. New cars can still suffer transport damage, wrong configuration or a drained 12V battery, so check the VIN, functions, appearance and onboard items vehicle by vehicle before shipment. Add VIN and order configuration to the batch checklist, keep the original materials for appearance, functions and warning lights, and re-verify after any change to onboard items and documents.
