Jeff,
Even with PCNA's problems & COA warts, it's still considered a valid collector document, & well worth getting for any nice 914/Porsche.
From my experience, you will need to send a pic of your case number if a 2.0 to get them to do the COA as a 914-2.0, plus you may need to follow-up with interior color codes if they get yours wrong from their reading of the Kardex (as happened with mine).
However, the only items which they'll accept as proof of options not showing up on their Kardex, would be the original window sticker, &/or
maybe the dealer invoice when new -
if it lists factory options &/or model number.
Any other pix & documentation will be a waste of time, since the dealers regularly swapped interiors (45 mins between 2 914s), Pirated parts & spare alloys off of cars (mine lost both its fog lights & spare ally), & other changes - not to mention what owners & dealers could add after the fact. So they tend to ignore current pix of an older car.
See Jeff Bowlsby's website for Model Numbers relative to included option groups (AG & PG), his Options Page for option numbers, & interior codes under the Tech Documents page of pdf documents....

PCNA used to give a discount if you have the COA (saves them work), & PCA members or if you "mention" Panorama magazine gets you $10 off the price.
Remember, even if wrong, they have a responsibility to correct errors at no charge, so if you run into problems, go up the ladder, & feel free to give me a shout if stymied, so I can tell you how I got mine resolved.
Good Luck!
Tom
