I would leave it alone. Porsche will not cpo cars with range 3 and over even if individual dealers do and then if (low likelihood) engine blows down the line they will not honor the local dealer's cpo.

Ran into same issue when a local Boxster spyder was being sold cpo by dealer in town and when it came to closing the deal they kept delaying showing me dme report for one reason or another and right when I said I wouldn't move forward and sign without seeing it they produced essentially similar report as above. I walked away and asked them how they could cpo car with other rev in range 4. No response. Basically if I had bought car and ran into any engine related issue it would not have been covered by Porsche NA.

it is amazing the divided opinion on this matter.
i, like you, feel the same way. That the car is designed to run below a speed (conservatively) and if run below that speed then there will be problem free operation as the 4.0 seems to have some really minimal things range with it.

I feel it is pretty risky to pay for a car and then face a bill of 80k for a new engine.

my race shop says they can test the car (scans, leak down and compression and scope the engine) and everything can check out fine but then a problem still can manifest and there is no way to predict it.

seems like the only insurance is to buy a car like this at a deep discount or risk the unknown.

Is there anything important to check over as a driver during a test drive on an over-rev car?
would there be anything obvious to listen out for ?

Why bother when there are so many of these cars for sale? You’ll get your *** handed to you when you go sell it or trade it in as everyone knows to check for these things and most buyers will either walk or require a significant discount.

Rapter

My thinking of a fair deal would be the current market value of the car less the costs of an engine replacement of roughly $65-75k (cnd). Thereby mitigating the risk of ownership and re-sale.

No, if there is a detectable problem it will show on the dash with a Check Engine Light or warning.

When it is time to sell, how will you feel ?

Rapter

Me personally, I would feel uneasy based on the response on this forum and other forums.

many people work very hard for this kind of car money and most are apprehensive, myself included, about financial risks.

no one wants to buy liability for 5 mins of awesome….

the idea is to protect myself from unknown mechanical risk which I why I posted up here to the collective knowledge of the forum.

I maintain a smart move for me is to negotiate a fair price based on engine replacement or politely move onto another car. I am not prepared to lose money on a track toy.

Overrev could have resulted in a hairline weakness in any moving part that was stressed for a tiny fraction of a second just close to its failure limit but not beyond and led to microscopic weakness or hairline internal fracture or weak spot that cannot be detected by any of the usual tools available today but that will fail at some point when stressed again. We should all be lucky to have access to dme report. Use the information to your advantage.
@rapter smart move is walk away because no money will be enough to cover for your time wasted car unavailable and knowing you don't have original engine with respect to resale. Nobody ferrets out cars with replaced engines instead of original engine when looking to buy these cars.

BryanCO

And above is the obvious answer. You value the risk as a new engine which a reasonable person would say is grossly excessive (and purely hypothetical as the car cannot be purchased for that).

silvertige

That is just ridiculous... just move on. No one is giving a 65-75k cnd discount for that dme. You're just wasting the sellers time.

catdog2

exactly, someone will buy it without even knowing what a dme report is

I'm not an expert on this subject .. but why would anyone knowingly want to own the risk .. a known risk if you didnt have to ....might as well buy one at auction on Coparts and swing away ..

They wouldn't do it "knowingly" ... but not everyone will ask for a DME readout. The dealer just has to find a sucker that will walk in, buy the car and find out about it later. Happens all the time. No one will discount a running car $70k ... they will just wholesale it and it'll eventually get picked up by the unknowing end user. Someone at some point will end up with a value haircut but even that is somewhat limited if they trade the car at a non-Porsche dealer, Carmax, etc. Now if the engine blows along the way, well, that would hurt - a new engine is close to $80K with a usable core last i checked. That's not including labor for the R&R. And with an engine that's been spun to 10,400 RPM (per the DME report), it can blow tomorrow ... or never. roll of the dice.

Again, the discount on these storied cars isn't enough to offset the risk and hassle most of the time. With so many cars for sale now, and a slowing market, it's not worth dealing with it.

People buy 991.1’s not knowing about the FF issue - and that’s a much higher risk than this car.
