Considering a 2006 Cayman S with 55k miles on it. Seller sent me these photos from when they had the boroscope done.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hard to say - most of them look pretty consistent with each other, which is not what you usually see with typical borescoring. I wish they would have provided the raw images instead of a picture of the screen like this. The last cylinder looks weird due to the discoloration - was this because it was taken at a different location on the cylinder, or something else? Do they have an explanation for that?

I think the last cylinder had some oil in it - possibly it had been sitting for a while and the oil crept past the rings (that happens in horizontally opposed engines.. some BMW motorcycle were imfamous for it..) Overall - I don't see anything of concern, but of course, the real proof is looking at the bottom of each bore from the sump... they start to score first at the bottom.
