There has been recent info posted regarding additional coupes made in the year 1990. it is a significant number of nearly 800 US and 4300 ROW. This is great news if another 5k coupes exist.

I know there are some I have come across that we always considered outliers but the info posted claims that they all should exist.

I am looking for 1990 coupe owners with vins above 1317 for the US only at this time. I am also looking for any of the 20 non airbag Canadian cars with vins in the 459xxx range.

It would be nice if we can figure out how many actually were produced. We know most all the other years but for some reason 1990 has some strange stuff going on Streather and other sources claim last vin of 1317 but Jürgen Barth shows much higher. His info is quite fascinating but has its erros just like every other source.

Thanks in advance

1990 C2 coupe...1376

Have you seen the list that someone here maintains with 964 vins? It's all years but there may be some info to glean from that.

I posted the North American non-airbag car VINs and country of registration from dealer network records. Barth has published all production numbers and VIN ranges. A few clicks on BaT will show you VINs that agree with Barth. What are Barth's "erros"? He is as close to the factory as anyone will ever get.

The search function here never works. I'm finding discrepancies in all sources including Barth's, I see a number of discrepancies compared to what the Porsche PCSS is currently showing. That is why I am asking. BTW the info you posted non airbag 964 coupes country of origin is incorrect according to the PCSS. They were all 900 code Tourist delivery and some do not show as ever being registered? All were C36 Canada so none were C02 US spec as you posted. I suspect lack of info input into the system but I am determined to find out more. Clearly the year 1990 had some strange stuff going on at Porsche. Is there any harm in doing some research of my own? I'm not bogging down other threads.

I have an early 90 ROW car. I belive its early cause it has a different lower dash pad. Gotta check the numbers

Here's 80 1990 Coupes on BAT...

Conversely, and much to my surprise, not a single 1994 NB C2 or C4 Coupe has been listed on BAT!

Dealer registration entry means that at some time a dealership in that country has had their paws on the car and recorded the VIN. Could be sale/service/ or just stopped by for an official Porsche fart in the driver seat and a tech recorded the VIN. A car could be made for the Antarctic market (obviously a C4 ) but if it visited a Canadian dealership then the CAN database would likely (not guaranteed) record it. Not being in the database doesn’t mean a car doesn’t exist, but being in it means it definitely does exist.

I’ve never heard of the pcss/dis database being used as a production authority. Has anyone told you otherwise? Anything Barth published is the final word.

You seem to be calling a lot of people incorrect while simultaneously posting verifiably incorrect info. The VIN info I posted is not incorrect. There’s no indication that Barth is incorrect.

I have one of the canadian non airbag cars, what do you want to know?

I have one of the 1990 C2's from Canada (#48 of the 80 brought in that year) that I purchased from BaT in November 2021. It is an airbag car though.

The 964 Study thread was an effort to collect that kind of information. There look to be around a dozen US ‘90 cars over that number.

Here is the most recent update from two years ago.

@9SIX4-C4 Is there a spreadsheet version that would make sorting and filtering easier?

Yes I have had multiple service managers, Porsche dealer general managers and a discussion with someone from Porsche at Tech tactics tell me that if it isn't in the system it doesn't exist. I do expect that not all the info is 100% accurate but I can't say that for sure. I also sat in on a virtual Porsche training class and the instructor made note of the system and its validity. So I guess I should throw that all out the window? I do suspect some info was input into the PCSS later as it didn't show in the system when I checked 15 or so years back. This is why I am a bit surprised and want to understand what happened.

I am only surprised that I am so far off on 1990 MY yet the rest of my info all corresponds closely enough with everything else Barth has published. I have been posting about this for closet to 2 decades. How many have asked how many C2 vs C4's and nobody has had any answers till now? I started this when Streather published his book and we found so many production number discrepancies. Then I found Redbook and other sources to be incorrect so I did my own research. I noted that vin sequences started with 061 back 15 years ago when every other (than Barth's) showed that those 60 vins were used and counted. I wish I had Barth's book back then it would have simplified so many things. There are definite differences between some of Barth's info and that in the PCSS as of last week. Which is the truth? I have pulled many vins off the PCSS to check cars I have done PPI's on and the info confirmed what the car itself provides. So call me a doubting Thomas but I prefer to confirm for myself. As I said you stated that some cars were destined for the US and UK. Yet all the cars all come up as C36 Canada and 900 Tourist delivery. There is no mention in any publication that I have found other than Barth's that mentiones 459xxx as a valid serial number. My understanding is these cars could not be registered in the US as 1990 without air-bags. So these things interest me.

I have no doubt my numbers are incorrect for 1990. I am happy to see the additional cars however are there 800 additional US coupes, I am determined to find out. I have found multiple 718 coded cars that have been double counted and would be interested in if anything like this occurred for 1990-91. So I don't see any harm in questioning anything. I have watched as friends went through this same process trying to verify tub numbers on special race cars using some of the best inside people. It is not an easy process. It took many years and some failures to determine the truth and this is from the people that lived through it and have direct access to the info as well.

I am sure there is more to learn but this is a new light on a long discussed topic here we haven't had some answers to until now.
