Is there a difference if the COA is produced in the US or
 

in Germany, in regards to a Porsche produced for the German market (ROW)?

The CoA is now obsolete, and replaced with the PPS and CTC. The PPS will often have reduced information, and you have to supply the engine & trans #'s. The CTC is an inspection in a authorized facility, and will verify what is present; but at 4 times the price. Each national distributor has a slightly different format and level of detail.
I offer an unofficial Report with greater level of detail.

Sorry but I am not current with the acronyms.

KARDEX - Pre 1970, the actual Porsche build sheet record.

COA - Certificate of Authenticity

CTC - Classic Technical Certificate

PPS - Porsche Production Specifications - this form specifically mentions North American cars only (US and Canada)


The end of the COAs imho got compromised because they no longer provided factory information for some items. Instead, they simply wrote the information you provided. Sounds like the successor PPS does the same thing.. It writes up what YOU present. Not sure if it gives an asterisk to denote something like *not original ;)


I am not sure how Porsche NA handles "grey market" or ROW car information. I presume they have access to a global database, but in real time (1980s primarily) the German companies practically banned ROW cars from service at US dealerships.

CW - Concour Weenie

Proper and Correct - CW with a pocket protector

Qtip - Something used to clean anything but your ears

Valve Stem - Something aligned with the bottom of your hubcap crest

Feel free to add to the above.

I think it used to be you gave Porsche the VIN and they sent you the COA with the engine and transmission numbers. For valuable cars, that meant it would be possible to forge the engine and gearbox if the original wasn't there.

So then there was a period where you gave them your VIN, engine, and transmission numbers, and if they all matched their records, they sent you the COA confirming the numbers.

Now the only way to get the engine and transmission numbers verified is to spend $500 for the CTC and have a Porsche dealer inspect the car and confirm the numbers. I think you can get a CTC for ROW cars. Here is a sample: https://www.porsche.com/all/media/flash/classic/certificate/en/6/

The PPS costs $100, but no longer has the engine and transmission numbers.
