If you can DIY, you can probably afford a Cayenne but it will likely cost a fortune if you continued as the PO did. I would pay to have the cylinder bores checked for scoring. Losing at the Porsche engine lottery will total the car, or double your investment... These are awesome cars but expensive to own, just know the risks going in and have a substantial slush fund if at all possible.

Anything else is a crap shoot.
Actually, I wonder if the oil analysis on its own would be enough to detect scoring?

I agree with the way it's treated is likely the difference between scored or not. Also, the recommended oil change intervals for Mobil 0W40 is way too high. If anyone was going farther than the intervals, they were likely driving with broken down oil.

I guess what I'm trying to ask is, if the cylinders are fine and aren't already scored when I purchase, is there any preventative things I can do to ensure it doesn't happen, or is it just doomed to happen no matter what? I guess what I'm trying to ask is, what is the root cause to even open up Pandora's box of scoring in the first place?

Bear in mind that you are buying a 9 year old car. Things will go wrong and things will wear out and break. The computers in it are at least 14 year old technology.
This one looks like it was treated well which is a good omen, but see above.
Unfortunately no one will be able to tell you for certain if you will have big bills or not. Cylinder scoring, whilst fatal for the engine, is still rare, so I personally wouldn’t worry about it too much.
If it is a good example,Someone else might buy it whilst you are having all the oil testing done (which might not be conclusive anyway).
So, I’d organise an inspection and just buy it and enjoy it.
Happy shopping.

Thanks for your response.
This is a 2009 CTTS.
Looks like he never had a problem with the battery, which is a good thing I guess; but I did see where he had to change the key/remote batteries like once a year---do those things really eat thru batteries that quickly?
If you send me your email, I can send you the cleaned up version of the records, so you can easily scan thru them to see if anything additional stands out?

Friday evening, during a trip home from the airport, a bright red battery/charging warning appeared. There was no issue prior to this warning.
Was able to make the 40min. trip home, but the lights were getting awfully dim.
I swapped out the battery on Saturday now all is well.
This is a 2009 GTS/65K mi. with an Interstate battery but no date to know its age.
Including the OEM battery this is probably the third battery in 9 years.

I don't know. I have 183,000 on my 2005 Cayenne and it has lived its whole life in cold winter climates. I think it is how it is treated. If garaged, allowed to warm up properly and maintained while being mindful of the cylinder scoring problem it can last a long time. Don't hammer on it til oil is warmed up, etc you should be fine. Also keep in mind if you are handy a scored cylinder is just time and a little money to pull, dismantle and have a shop sleeve the engine. If you aren't handy, it would really suck and cost more than vehicle is worth.

1. Clearly the owner did not regularly check the oil
2. This car burns enough oil where that will be necessary
I see they drove it until the oil light came on and then took it to the dealer

My 09 gts was my first porsche. Bought at 100k miles. Cold climate in NY and ohio, now in Michigan. 15k miles into ownership, no major issues, but it is not my daily. Blackstone analysis reports oil is excellent every 5k miles. I always wait until oil is a operating temp before I go WOT.
Having to do it all over again, I would probably get a turbo. Speed is addicting.

Even worse, I think the coolant warning light was addressed at the same time as the oil warning light. How long did this fool drive around with the warning lights on? Until the keyfob battery died causing an actual inconvenience for her?
Out of all the jibberish posted, I think I see maybe 3 oil changes listed. I'm guessing they're the type to only go by the dash messages and the car went 10,000 miles (and maybe years) between changes.
And from all that's been done to it from day one (excluding the weekly tire swaps and tire repairs)...that thing appears to be a lemon.
