Preowned question

I'll let someone more knowledgeable about Certification for the CPO cars.

On the issue of a PPI, you're considering the purchase of a very expensive car. Throw a couple of hundred at it by having a solid inspection done along with a 4 wheel laser alignment (too see if it's been wrecked and not repaired properly). If I were you, I'd also insure that you discover how many stage 1 and 2 redlines the engine has endured just for your own knowledge as a baseline... and to see how the last owner(s) treated the car. If it's been stage 2 redlined a lot or recently, you can walk away. You find this out by having it hooked up to a OBD reader from Porsche.

(BTW, the alignment is a personal thing for me because my car had a bent subframe in the front and a bent strut in the back from a curb hit + spinout that was never shared with me when I was buying the car. Evidently, the previous owner let it get away from him and a regular PPI would not have discovered this).

Hope this helps!

BTW, I would only buy a CPO very low mileage Box S next time around. I've had it with Porsche's "high performance plastic" parts that wear out far too early. Porsche can pay for them under a 100k warranty next time around. Love the car, but hate some of the crap they bolt to the car in the name of saving a few ounces here and there.

The CPO warranty is something that the dealer purchases from Porsche. To do this, the car has to meet criteria that Porsche sets, ie, only so old, only so many miles, no frame issues etc, parts up to snuff.

When a dealer buys a car that meets Porsche's criteria, they do their own inspection and decide if it makes economic sense to do the CPO. This would require that they bring all wearable parts up to speed, tires, brakes, etc. and they pay Porsche the fee of around $2000 for the warranty.

They then add about $5K to the price and buff the baby up.

That is about it.

You can draw your conclusions on value of this process. Sometimes, if a car is not a CPO car, it is simply a matter of the car being too old or having too many miles.

Other times, it is an issue of the costs required to bring the car up to standard, weighed by the dealer's thoughts on what the car will bring.

Good luck with your decision.

I have been having fun with my Durametric software/OBD reader, I checked with them and it looks like it will sorta tell you how much the engine has been in at and beyond the rev limiter. The software gives you the number of ignitions the engine has been at the rev limiter (Range 1) and beyond the rev limiter (Range 2). I am not sure how this information on number of ignitions as a measure of time at redline differs from the information from a Porsche OBD reader.
