Would you buy this car? (over-rev data)
Hi all,
I am looking at a 997 turbo with 38k miles on the clock. Here are the results of the DME download over-rev data:
Total engine operating hours = 436 hrs
1 @ 408hrs 4591
2 @ 402hrs 609
3 @ 332hrs 89
4 @ 59hrs 26
5 = zero over-revs
6 = zero over-revs
Could anyone give me some expert advice here? It would appear that it requires a compression test. It has hardly done any miles since it's oil change with the current seller, so I guess that would mean that oil analysis would have little value? Would you buy it or not? The dealer is offering a warranty, which covers the engine, for 6 months, but I will only be doing around 500-1000 miles per year in it.
Many thanks for your help.

I would, the range 4s are minimal and old and the rest looks fine. Just based on that I wouldn't think it would need a compression test, either.

Good catch, I skimmed over the miles. That is a pretty low operating hours for those miles, making for an extremely high average speed. I don't know what to make of that, the report is cleaner than most tracked cars' and for it to be that high it would have had to be living at 100mph most of the time. Makes me wonder about some tomfoolery with the DME, or was the engine rebuilt and they reset the computer?

According to the many experts on here, RUN FASTER! Perfectly fine car. I know a guy that knows a friend who's best friend knows another guy who can make those values read whatever you like! $500.00. No history of anything after "they are done". You just have to ship the ECU to Alemania. Germany. With that being said, it proves that the over revs registers don't have any implications whatsoever. All freaking nonesense if you think about it. Buy the car and have a quality PPI.

There’s an endless supply of opinions on DME Reports. Sometimes, I think a perfectly good car is bypassed because of DME Reports. Let’s say you do buy it... You come across as a person who’d have buyers remorse once you drove off the lot, I could be wrong. Since you’re already having second thoughts. I would look for a car that has no stories or excuses. They’re out there, however a PPI is always a good idea and worth the money. Unless money is no issue for you, an extended warranty that you purchase yourself will provide you with comfort. Good luck on your search....it’s one of the things I love doing... JB

Nothing wrong with those over revs. The hour counter on the other hand is a huge red flag unless it can be explained & verified that is wasn't altered with malicious intention. But make no mistake, it's been tampered with.
If you pass on the car, you should post up the ad or details of the car / dealer so that people can ensure they're fully informed if they are looking at that car after you.
