Over rev in a gt4?

Ya the older I get the less interested I am in buying cars privately. Too many lies I uncover (looked at a m3 for a friend. Never been repaired! all factory paint. uh, why is the entire front end repainted? oh for rock chips!. Then why is the 1/4 panel also painted? oh it was scratched. no, I can tell it has body filler under the paint from a repaired dent that was quite significant as I can see the sand scratches from them finishing it improperly... and she didn't buy that car).
Definitely not interested in buying a car from from a non CPO dealer either; if it was good what's it doing at a kia dealership?
If it's a car that's cheap or I plan to only own for a little bit i'll roll the dice on buying site unseen if it makes sense to do so, but on anything expensive or that is a keeper, it's gotta be a CPO at the dealer that sold that thing new.

@Zhao I've found paint work on CPO BMWs before, unsure if Porsche is different. Bought some great cars from individuals. I just don't buy sight unseen period.
New cars and CPO cars can have a repair paint job as long as it is below a predetermined value.

CPO also costs money to do and can have some **** requirements, like requiring OE tires. Dealers often aren't going to want to put 2g worth of tires on a car that needs 4g in the bodyshop and 3g in the shop. Often better to send that to auction or sell it as non CPO. So you can find junk as CPO cars or cars with long histories, but your odds are much better of it being a good vehicle when it's a CPO.

so that’s the type of thing I’m trying to understand. It looks like it was one over rev. Both 2 and 3 recorded the same minutes. Lord knows I’ve missed a shift before and probably will again. Sounds like the 718s only have 3 levels of overshift recording where as the older gt4’s had 6

Who pulled the DME data? Selling dealer? I’d take it to an Indy for a PPI and DME pull.

is there a way of confirming 6 zones? If there are then it’s back over the table. My local sm said there were only 3

It's very unusual to kill a clutch in 20k miles, right? That seems like a sure sign that someone really beat on the car and didn't care for it at all. I'd be worried about other issues cropping up in the future i.e. parts that have been stressed but not broken yet.

Double check, but I think with zone 3 ignitions, the car can be CPO'd if it has been so many operating hours ago.
That data should also be in the DME report. The more recent the event was, the less inclined I'd be to consider the car.
Of course, with 20K miles and over MSRP? Not a chance, even if perfect.

I sold my 2020 manual Gt4 with 8 range 3 hits, they CPO’d the car and sold it 1 month later. I asked the service manager about over revs, he said range 1-3 is no issue, range 4-6 will be based on how long ago it happened and then Porsche Germany has to approve if they can CPO it or not.
and if you don’t know, the 8 means ignitions, so 1 full rotation of the 6 cylinders plus 2, so like a fraction of a second, which is nothing, as the service manager said.

The minimal range 3 overrevs aren’t a huge concern, especially if they were many hours ago. You can check this by comparing when the over was versus total hours.
The larger concern is why the clutch needs replaced after only 20k miles.

There are 3 ignitions per revolution, so 440 ignitions is about 147 revolutions beyond 8000 RPM. Probably around a second.
There should be more zone 2 over revs.
Zones 2-6 are mechanical over revs.
I’m pretty sure the last modern Porsche to only have 3 zones was the 996/986 series.

not really, that’s why it’s a replaceable part, new clutch and you are good. Rest of the car still has what, 3 years warranty bumper to bumper. If you plan to keep longer then 3 years, either get extended warranty or sell it.
it’s good tools to use for bargaining for a good deal.

Porsche will CPO zones 1-3, its not an issue. Lots of tunes actually raise the RPM limit by a couple of hundred, there is overhead in these engines. It may be something as simple as the cart bumped the limiter on a down hill, doesn't indicate its necessarily a miss shift.
Clutch is a wear item, its doing its job. That wouldn't bother me either.
As the fed dials back QE the likelihood of a hard landing increases, when this car market tanks its going to be quick and a lot of folks will be left underwater. Personally I would not pay over MSRP for a car with 20k miles but that's just me
