For Tai 7 Underbody, Battery and Water-Exposure Inspection, reconcile route and exposure statement, front-to-rear underbody image map, PHEV or EV component identity, diagnostic and isolation evidence, repair and repeat-inspection record. Mark each item verified, seller-stated, estimated or unresolved, and put a responsible person and expiry date beside the open work. Keep commercial rows separate so a change in one assumption does not silently rewrite the whole conclusion.
Immediately before payment or handover, repeat “Establish the route and event” and confirm that the candidate still matches the reviewed record. Preserve the VIN, odometer, visible condition, keys, documents and relevant energy state. If the vehicle or a material specification changes, close this file and begin a new one.
