Well, it’s really not much more time than an oil change.. it’s the proper way to check but ya it could be a tough thing to convince someone..
it’s not very common tho on 9A1 motors… almost unheard of…
according to Jake Raby the pan off is the full proof correct way to really know… I didn’t make this chit up

After my experience having 5 scopes done from spark pluig holes on 997 S cars I wanted to buy, IMO a ridiculous argument and makes no sense to insist a scope needs to be done from oil pan on 60K+ mile 997.
I'll leave it at that.

Truth be told, these are 15 year old performance cars, and any 15 year old vehicle is prone to some sort of wear and tear. I've posted this statement a number of times, I see bore scoring as wear and tear. Just go into every purchase with your eyes open. Get a PPI with a bore scope, or don't and budget $20k for a rebuild.
And don't doomscroll the forums. A lot of "Porsche people" can be exceedingly pedantic or obsessive about this sort of stuff. There's also a huge sampling bias, given the self-selecting nature of the discussion: everybody who has this or any other issue with their car (or worries about it) comes here to post about it. Meanwhile, almost nobody comes here to talk about how they drove 1000 miles today and nothing broke (except new owners and Land Rover aficionados, I guess).
Do your homework, be well informed, but don't stress about it. Go into this as though you're buying a $100-150k car (because at one point, it was; pay up front or pay on the back end). Expect it to depreciate. Expect things to break. Expect all of this to cost money. You might get lucky--and you might take every possible precaution and still have it go the wrong way. If the money isn't there or you don't feel like spending it, maybe look elsewhere, and that's ok too; a 911 of any given type honestly isn't 2-3x the fun of many sporty cars that cost 30-50% as much.

Exactly. 2009 and newer 997.2's are starting to pop up with bore scoring.

With good care & management, he feels confident that the engine has years of life left in it before it becomes noticeable. Fingers crossed, but I went into the purchase with my eyes open.

Not until the 991.2 and 718 does the bore scoring issue truly go away. Porsche switched to an APS bore coating, SUMEbore specifically. The 918 was the first model Porsche where SUMEbore was used on the cylinder bores of the Alusil engine block.

^^^Hopefully we see less 997.2 owners preaching/claiming there is no Bore Scoring found in their engines. Gets tiring but understandably they do it out of fear.
997.2 owners please feel free to request our Therapy meeting schedule.
