500 unknown miles???
My friend bought an 09 911 S coupe as a new car from the dealer that had 15 miles showing on the title but noticed at delivery it was showing 500 miles on the odometer.... He took delivery because it was such a good deal at the time but over the past 18 months it has been making him crazy not knowing how the car was driven over those 500 miles.... He didn't know about DME searches at the time and because the car ran perfectly it didn't seem to be a problem....
I know it's eating away at him but he doesn't want to open up a can of worms.
In this case... ignorance is bliss....

Just don't let the Porsche dust cloud your vision. There are lots and lots of cars out there.
I would recommend buying a CPOed car or extended warranty on any of these cars.

Thank you everyone for your replies. I've come to the conclusion that I will step up and buy the vehicle. Yes 35 mph is a high average. The negative interpretation could be ridden hard, the positive interpretation could be highway miles.
I am buying the car from a out of state non Porsche dealer and had the dealer in the same area perform a prepurchase inspection. The dealer feels it is a clean car and could not find any issues. I plan on pitting a warranty on it and enjoying the car.
The car has 1,037 hours and the high rev occured at roughly 500, 600 and lastly 800 hours. My thought is that the car has added an additional 25% more miles since the last high rev incident and still checks out ok.
The warranty period ended this December and had only three warranty issues, a deformed piece of body plastic on the front bumper area, an issue with the horn and a fuse. I would assume an owner who is looking at the expiration of the warranty would fix any problems before the warranty expires (just an assumption of reasonableness). No additional warranty work done, points in the direction that there was nothing wrong with the car. Even if the owner's plans were to dump it after the warranty, they would have fixed everything they could for free to make it sell for more. Assuming the warranty was not voided.
My thought on the PCNA warranty being voided, is a dealer will take as much warranty work as they can. As such they aren't going to flap their arms too much to point out things that might take incremental revenue from them.
I also spoke with my local dealer's service department. They said a short high rev incident can be a quick slip. He said he had never heard of a warranty being voided over this and was not concerned with the read out.
I do appreciate all the thoughts and comments and it did help me weigh my opinion. I tend to be thorough in my decisions, my money doesn't come easy and I always listen to other's opinions. Wish me luck! I hope I love the car and I plan to drive and meticulously baby her!

I wish my DME looked like that. Most of the people on this forum are preserving their cars for the next owner. I would read to much into the DME scan, I would be more conserned with a car that has limited use. Buy it, drive it the way you want to, and sell it for what ever the next guy is willing to pay. Along the way you will have a lot more enjoyment out of your car then most of the people that spend their time telling people to run from a perfectly good car.

Thanks!

Enjoy it in good health and have a blast, man. I'm sure the car is fine, these cars are built "ford" tough!

On a 4 cycle engine there is one ignition event per cylinder every other rev. So on a 6 cylinder engine there are 3 ignition events per rev, not just one. So you would take the number of ignitions and divide by 3 to get the number of revs in the ranges of concern.

7,400 rpm = 123.33 rps = 370 ignitions per second (7400 / 60 x 3)
so if DME reading was 5487 ignitions then the overrev grand total time was 14.83 seconds (5487 / 370)
Unfortunately from the DME readings the hour of occurrence indicated just tells you the last time an over rev occurred. So you could have had 100 ignitions at hour 1 and 5387 ignitions at hour 1,000 - unlikely but the DME doesn't provide all the info.

Isn't it highly improbable that there was 1 ignition in range 5, more likely an error?
