I would either have a tire shop do an inspection or read up on what to look for as far as age damage is concernedor check and see if there is a youutube video on the subject.
You seem to have a handle on the oil but remember to have the shop do a test on the coolant and drain the old windshield washer fluid.
As far as a comprehensive PDI type of check list, there are several PDIs available on line. For the most part the inspections are easy to do and a mobile or shop tech is not needed.
Keep checking back here for anything you have questions on.
