I recently noticed this number (17156) stamped on the front left of the A-pillar. It's not a plate, its stamped directly into the body.

Can anyone tell me what this # relates to?

Thanks

No further info is available, I think Karmann used these numbers to track each chassis as they were made. They didn't use the VIN, that was for BMW.

Im trying to find any other stamping, if there are any....?

The car has been extensively restored, and any chassis plate has well rusted away....

The only thing that will give you some history is the VIN ....do you still have that ? ( stamped on the firewall ...RHS ) . If you don't have that , it will be stamped on the engine block, however, that's only of use if you know for sure it's the original engine .

Frankie, A lot of what you need is already here on the Forum.

Awesome - thanks Chris. The data in the link you provided is the same as the data I've researched elsewhere - but I'm informed by others the lists are incorrect... (sigh)

Can I get an authoritative answer from BMW?

Probably not these days. The BMW Group Archive are moving. Official information is they delete all incoming mails unread and will not be back in business until the end of the year. I spoke to a gentleman there in June or July and he told me the same.

but I'm informed by others the lists are incorrect... (sigh)
If I may say so, @HB Chris' lists seem to be quite accurate.

Do not trust the Wiki, we have the most correct list. The others show 200 too many US 2800CS and don’t include the 21 race cars. The other is the 2 CSiA which I think are already included In the CSi 226xxxx VIN range. Can you tell me where our data is incorrect, I’m all ears.

This is the problem... people are happy to contradict the data but unable to provide the 'single source of truth'

Hi @Frankie,

Hoping I can help a bit. What exactly are you searching for? The VIN range data on this site is correct. Much time was spent by @HB Chris to validate and correct the range.


You won’t find your build date, original color, original destination on the forum however. BMW provides this information but has not been responsive during COVID.

4330066:

This is the very start of the RHD 3.0CSA range, as indicated in the VIN FAQ that @HBChris posted.

It is included in the registry as a build
hear 1973. This corresponds to the VIN list. It is advertised as a 1975, but that date doesn’t match our published VIN range. This likely a benign date flaw likely tied back to some late registration. It’s pretty common.

The car is a facelift model with late seats, etc. For euro cars this started in 1973 as indicated in the FAQ. The car is listed and registered as Amazonas - a facelift color available in MY 1974+, but for euro
cars that could be 1973.

The original Karmann tag on the car supports that the original color is Amazonas, as it is stamped 76. The tag also indicates that to no surprise, the car has been resprayed.

The VIN plate is original.

The import tag says 1995 which renders the approximate import date of 1998 in the registry incorrect.

VIN’s aren’t necessarily built in sequential order at the vehicle level as shown below, but as a whole the data supports that the progressive VIN ranges tie to a progressive build calendar.

Process of elimination. As you can see, nothing near 1975.

433010 - Built 12/1973


4330013 - Built 12/27/1973

4330036 - Built 12/20/1973

433052 - Built 12/14/1973

433066 - Built 12/1973

4330179 - Ask @Gazz

4330182 - Built 06/06/74

4330194 - Built 06/06/1974

4330195 - Built 06/74

4330199 - Built 10/74

4330207 - Built 12/74

Hi, thanks for this - provides great clarity. I was researching the car to purchase and confused by contradictory information... now I know where to come I'll ensure my future research starts here (I didn't know of it prior to this).

I really appreciate the effort of those who put this together... could it stand alone on the website as a register for other enthusiasts like me for easy access and reference?
