The red flag would be a "mileage to operating hour" ratio..

So, if your car has zero over revs but has averaged 300mph over it's operating hrs, something may be amiss

I know I'm the nerd here, but if the ECU/Odo's been doctored, the average MPH will actually go DOWN. Fewer miles over the same number of hours...

It's actually a very good rule of thumb. Take your daily driver, reset the trip counter and let it run for a week or two. That long-term average speed on is probably a reasonable baseline for traffic speed in YOUR city/location. The car you're buying shouldn't deviate significantly from that number. I'd be worried only if it comes out significantly BELOW that average.

It can be done but NOT with the dealer's (see Porsche PIWIS tester) equipment. Now, if a dealer is crooked he can do it with aftermarket methods.
They can also change the ECU without copying the old data in the new one.

Unfortunately, with the proper program you can do anything in the DME. Anything..and leave no traces.

People buy GT3s (RS'es in particular) to track. And unlike a girl, there isn't a "seal" that you can inspect per se to establish provenance. In my book, these cars are all priced with the assumption that they've seen track use. It's just a matter of condition.

Those who advertise untracked GT3s for sale gets all sorts of red flags in my book. It's like advertising a virgin in a brothel. It just doesn't fly.
Yup

Agree, altho a recent deep dive into the PIWIS dump from my own car revealed LOTS of little easter eggs. Apparently there are separate counters for "Driving Cycles" and hours to various types of events (overheating, etc.).

You're right that a sophisticated guy with a flash programmer can STILL doctor up the whole nine yards, just that there'll be lots of bases to cover...

I have instructed in quite a few Gt3

When someone is learning how to heel toe, or doesn't know how to do it it is very hard on the syncros and axles / drivetrain / clutch / pressure plate.

Second how often are the fluids changed on a rookie car......I've changed the oil on some of my beginning friends cars....they didn't realize once the service light comes on its way way too late to change the oil. Oil is cheap engines are expensive, I do mine every four track days

The best cars out there are bought from an owner you trust.....I'm not sure I'd buy a used gt3 from a mystery owner.
