Answers:
When it was painted? By my eye, the roof was given a fresh coat within the last few years, but before I purchased it. On the body, most of the paint you see is original, but with spot touchups done here and there.
Bump/bulge on rear driver's corner? I wondered the same thing when I was thinking of buying this one - the seller told me they used to have a little step/stool thing that would hook on there and from using it over the years caused that bulge. I've never seen such a thing myself but I carefully examined the interior of the corner/outside of the corner etc looking for rust repair or bondo (with a magnet) etc and its solid on both sides.
