In the process of purchasing a used 997.2 C2S. Inspection report came back with all 0's on the rev report.
Feeling pretty excited about this car having been so baby'd. Anyone ever see a 0 rev report?
Any tips/questions etc... that I should ask before pulling the trigger?

Otherwise, we have found our 997.2 C2S to be very satisfactory and I can't think of a single caveat. Nothing at all to "look out for." Great car. You'll love it I predict.

Actually you can get slight over revs into range one and two with PDK saw it on a friends Cayman BUT Range one and two are almost normal and Porsche does not get excited until you start seeing them in Range four and above. That is according to a PORSCHE master tech So enjoy your new toy

I am not convinced that ^ is true. While it is true that PDK will not allow a downshift that would initiate a mechanical over rev (a.k.a. money shift), I believe (and this is my personal opinion) that over revs can and do happen on a PDK. I have never seen a DEM readout of a PDK car, but I am betting there would be over revs if the rev limiter has been reached.
Excluding "missed downshifts" (a.k.a. money shift), why would a car with a manual transmission have over revs when the car is accelerating and hits the rev limiter and a car with PDK not do that? That makes no sense. They both have the same rev limiter and on both cars the fuel supply is cut off once the rev limiter is reached. So why wouldn't a PDK equipped car also record over revs?

On the other hand, all devices have failure modes. So I'm sure the PDK cars are recording the same DME information, in case they need to diagnose one of those failures. They just can't blame the driver in the case of a PDK car that blows a downshift.

You should also look at the DME report, take the total miles and devide by the total hours on the car. Does the math make sense for average MPH and the cars condition? Just a tip to check the "accuracy" of the reported total miles.

I looked into this in good detail. Over- revs can onliy happen on missed downshifts due to mechanical over- revving of the engine. Rev limiter otherwise cuts you off on engine acceleration. So this just means car hasn't been driven too hard or tracked.

This is not true. You need to look into things more. You can get range 1 and 2 over-revs without missing a shift. Common, and normal. You can also get over-revs exceeding range 2 with a spin, since the rev-limiter does not protect when the engine is spun in reverse. So, the are 3 ways possible, not one as you stated above.
