911 GT3 operating hours vs mileage

[civiclegend]

I've been looking to change to a more involving and direct car for so long it's getting ridiculous. I'd finally settled on the idea of a 997 GT3, and have done much research on the subject.

Went to see a few, decided I'd found 'the one', from a very decent seeming trader, then I asked for the overrev report.

There has been one incidence of a cat. 4 overrev in the car's history - backed up by the corresponding cat 3 and 2 both having been buzzed at the same time. Cat 4 for 70 ignitions. This happened 74 hours ago.

This does not completely put me off the car, but the mileage (47k km) vs total logged running hours of 474 seems a little optimistic, doesn't that equate to nearly 100 kmh (60 mph) over the lifetime of the car? I would have thought that a principally road based car would never manage more than about 30-40 mph?

Would anyone else care to share their running hours vs distance travelled? Has anyone else got close?

Cheers chaps and chapesses.

Its a Swiss/German (having spent half its life in each) car. So it could conceivably have done some serious Autobahn smashing, but those that drive those roads know they're rarely that fast... pretty jammed up, much like the UK, much of the time!

Well, that is indeed where I'm at with the dealer... either he shows evidence its been done, or does it, or I go elsewhere quite happily.

Shame, as I really wanted a wed wun...

You did notice the German part too?

But yes, I am skeptical, hence asking the question.

Amazingly, GT3 values are a little softer here in sunny Switzerland, maybe because it is harder to drive them to their potential unless you live on the German/Italian border! The 997.1s I have been looking at are similar mileage to that, but equivalent to about GBP 70k. Ok some of that is mk1 vs mk2, but definitely feeling the winter blues in the values here. There is a black 997.2 with 55k on the clock for GBP 67k.

Believe its /3 for the revolutions, and you calculate basis the max allowable engine speed.

23 engine revolutions. Thus 0.16 seconds.

I`m sure not really a reaction but more of a horrible instinctive feeling of what you`re about to do, almost before you`ve done it and clutch back in instantly. Sadly momentum carrying the revs over the threshold.

Thanks S1MMA. This guy doesn't have a story consistent with the car's ecu output as yet - which worries me more than the single overrev event, giving him the benefit of the doubt for now, but have full skeptical-goggles on. Looking elsewhere too.

So, some progress. The car in question has been to Porsche for an inspection, and amongst other good feedback from them, it turns out the ecu logfile sent by seller of the car, (in turn sent to him by his mechanic as saved on his computer) was out of date - by some 2 years and 150 running hours. So the logfile as read by Porsche states over 210 running hours since the incident, and over 620 hours in total - so the average speeds and the rest of the story now fit.

This is good news, the car has indeed been warranted twice since the incident (not Porsche but a decent independent), and will be again.

And I didn`t really want an R8! (Although I was kidding myself I would have been just as happy with one).

T.... tomorrow there will be!

Crappy phone upload, but there you go! Utterly immaculate. Worth the stress.
