This COA was shown with a car in the classifieds section. I'm curious about a couple items listed.

Radio-I thought ALL radios were dealer installed, how would Porsche know which one the dealer added to a car?

Bilstein shocks-weren't those standard?

Vented brake rotors-likewise, weren't fronts standard on a /6?Click to view attachment

I don't know the answer to your questions but I have one of my own; how does one get a COA in the first place?

The records for the 356 were all on codex cards, hand transferred to these COA documents.
It may be possible that the data collection from the dealerships sent back to HQ got much better in the 70's versus the 60's.
That may explain dealer installed options showing up on these COA documents.

COA's have changed over the years in appearance and what they share. The one pictured from 16 yrs ago is formatted differently from today's. That said:

radios were available from the factory.
boge struts were standard, bilsteins optional.
6's have vented front rotors, solid rear rotors.

Kinda like when you read a new car window sticker and they put things like "wheels" or "seats" as standard. no shit sherlock.

I am told nowadays, you need to supply the engine # of the car in question, and when they create the COA they add next to it only if that number is matching or not, rather than tell you the number it should have.

Not a lot of info on #41. from Feb, 2007

Kinda on the fence about ordering one, really what's it going to tell me that I don't already know...

Same for me from May of this year. Although will be contacting Porsche to update it to the correct color L96M on the chassis plate.

Pretty much worthless unless you're competing in a PCA Concours.

If your six has it original Eng. you have the number from the factory. More than bragging rites to some buyers. I don’t have the original Eng. but I knew that, as I had the original service book with my car so I had dates and numbers. My COA did not have as much info as others. I do not know if that was because my car was so early?

If you do have the original engine, will the COA confirm it? I have no reason to believe my engine isn't the original so was hoping a COA would confirm. Also looking for confirmation that my car came with performance group but NOT appearance group. If not, then I'll need to alter my restoration plan a little.

I also have the original warranty/service book but they didn't bother to fill in the engine number.

I ordered my COA in April 2016. I sent a note with the request form listing every number I could find on the car.
My COA came back with a transmission number listed which I understand is very rare; I'm assuming that either the number matched their records or was in the allowable date range, so they included it.
There has been some other discussion on here about engine numbers, I think if the number you provide doesn't match their records, they will either leave it blank or fill in what they have listed.
As to value of the COA, some day my car will get sold. Either by me or my heirs. Matching/original numbers still commands a premium, so for the $100 it costs for a COA, I figured it was worth it.
