Buyer's and Routine Maintenance - Inspection Checklist for T@b 400

I've shared with others the checklist that I created prior to the purchase of a T@b 400. I had a bad experience with a dealer but a wonderful experience with a third party seller that made the purchase exceptional. After the purchase, I started looking at the various issues, complaints, troubleshooting steps and what would constitute a rigorous periodic maintenance routine for my "new-to-me" 2022 T@b 400. I hope this posting will assist others doing a pre-purchase inspection and or the regular and routine maintenance.
