Is there any way to tell a device's history with Apple? A 'good price' is being offered for a s/h [edit: wifi only] iPad Pro (2017) in my local city for inspection, purchase and collection. The coconut battery check shows minimal use for device manufactured in January 2018. The seller makes use of iCloud with his AppleID, and says he can demonstrate log-in. However, the seller is in a bind as not the original purchaser and has neither box nor receipt but was given this by a family member. Clearly I can back out of this, but the price is a good one relative to the AppleStore refurb price - albeit that gives much more by way of assurance of provenance, battery, case & warranty. Any advice on how to progress? In particular, what could the seller do to assure me of provenance?
