I don't know the previous owner so can't comment, but my car came with a folder full of receipts, most of which were lies, including a full service inc filter change just 5 weeks before I got the car.
After really getting stuck into sorting the car when I replaced the "new" filter it had a date on it, 12 years previous, also had according to receipts diesel transits parts on it!!
It may well have been changed if it looks new it's ok, just do everything else and see what you find.
