I've been looking at the 981 Cayman GT4 since it came out, not being in a position to get an allocation when new (like most), and then waiting (and waiting some more) for pricing in the used market to fall into the realm of reason. It seems that prices are finally creeping down, and there is a decent selection coming into Spring.

My intention would be to buy a GT4 as a CPO from a Porsche dealer, preferring to keep to the lower end of the pricing spectrum because the pricing seems to be heavily driven by mileage. Obviously not all mileage is the same as some cars may have seen heavy track use - I would be taking the car to the track several times a season, but it would mostly be used for DD and back road jaunts.

This being said, I just got the DME results for one of the more promising leads I've been looking at and there are over-revs in ranges 1-5, specifically:

Range 1: 363 ignitions @ 318 hours
Range 2: 10 @ 127 hours
Range 3: 12 @ 127 hours
Range 4: 36 @ 127 hours
Range 5: 77 @ 127 hours
Range 6: 0 @ 127 hours

The car currently has 566 hours (20k+ kms), so it's been over 400 hours since over-revs in ranges 2-5, and they all happened at the exact same time, so obviously just one event. The range 1 values seem to be a few times when it's been redlined.

Seems that dealer may still be able to CPO it because so many hours have passed since the Range 2-5 event. Not sure the risks given how long ago it was, and if under warranty then it seems that the greatest risk is to re-sale value.

Any thoughts, insights? Should I take a pass, or use these results to drive a deal on the car? It's already the lowest-priced on the market and is otherwise in good shape with no accidents and highly spec'd (sport buckets, PCCB, etc.).

(NOTE: I accidentally posted this is the general 987-981 forum first, so forgive me for the cross-posting).

 

If the dealer is willing to CPO, that is great peace of mind... otherwise Rev 5/6 are deal breakers for me.
BTW... dont assume all the oevrrevs happened at the same time (127 hours)... the report only shows the last time it happened (in your case, its looks probable though).

Good luck.

 

CPO a plus, having that report is a negative that, in my view, wont impact the reliability of the car given that the higher ranges happened so long ago, but will impact the car's value if you want to sell it.

 

 

Thanks for the feedback all. I asked the dealer about undertaking the additional investigations (compression, leak down tests, etc.) but haven't heard back yet. Depending on what they say and the results, I'll seek some further feedback here and re-evalute...

 

It seems like this would give you a lot of negotiating leverage. My precisely 2 cents is this wouldn't scare me off at the right price. Factor in a rebuild cost into your offer.

 

Resale will be the issue. Too many nice cars out there without a DME report showing those ranges.

 

US dealers would perform all of those tests before they offered a CPO on an engine with range 5 over revs. Nevertheless, as others have pointed out the resale value of this car will be affected, especially in the future when a CPO isn't possible. Unless you get a significant discount, I'd walk.
