I just had a good look at this car in Pittsburgh last month. If Darth Vader had a GT this would be it....super cool with the GTS quarters and no side moldings.. and probably a one-of-one GT with XX8. I think somewhere on here there was a way to check a VIN and options that would return "number of cars delivered with option x" feature.

+1.

This is a very rare and unique car.

I had the chance to see that car few times.
And meet Steve at the same time of course.

Hope Steve will get another 928 and see him again at future events.

Congrats on your new purchase.
Hope to meet you also.

Andrew/Drooman - As you know this a "Holy Grail" car for me... Given my 9/28 birthdate, nuff said...

According to Jarrod Wise of the 928Registry, this is a 1 of 1 car for the North American market.

It is also clear that there were other GT/S4 XX8 wide bodies built for other markets (most notably Japan) and it will be interesting to see where this one fits in the numbering sequence. From what I can see, it looks like there were 265 1991 S4 & GT's built for the US/Can after this car. Where it fits in the sequence of ROW wide bodies is the question of the moment and I hope Jarrod or my friends at Porsche can shed some light on this... Perhaps your friend in Germany?

I like to speculate that it is the first wide body for all markets, but that remains fantasy for now.

Once again, a special shout out to Steve H. for his stewardship of this car. Steve is not just a Porsche enthusiast and driver, he is a great guy and I am honored to put some time and energy into this piece of 928 history.

SeanR, Wisconsin Joe, Bertrand, and "The Peanut Gallery" of photo requesting friends.

Thanks for your kind words. I look forward to meeting up with all of you "Down the road".

This car has a few missing pieces/parts and some deferred maintenance to catch up on. I will be leaning on and learning from all of you...

Cheers!

Dave - as I mentioned in my PM to you, I can only find one US/Canada market car with option code XX8 - yours! So it appears to be the only one of 387 cars built for our market with this option.

However, the ROW build sheet data reveals 90 other cars with this code. They're all 1991 models, of which a total of 1,650 were built. Of these ROW cars with the XX8 code, the earliest serial number with this option is 800191 and the last serial number is 801709.

Congrats again on your purchase!

What an exceptional car. Steve was a good caretaker, and I have enjoyed seeing this beauty up close on a number of occasions. Looking forward to see you bring it to the next level.

Jarrod,

Thanks again for the great information and your time. It was nice to learn that the 09991 option means "Manufacture from the Exclusive Programme" and to know that there is an undiscovered option on my car 09981 to learn the meaning of ;-)

As I look at the production tables for 1991 928's - I observe that the range for S4's and GT's combined is:

ROW - 800061-801710------1,650 cars

US/Can -810061-810447------387 cars

The first ROW car with XX8 is #800191
The 1 US/Can car with XX8 is #810182

My #810182 XX8 build date was October 8th 1990, so it is a relatively early car.

Can you check the build date on the ROW #800191 car and if it was a GT? If mine is in fact the first wide body S4 or GT produced, it would add significantly to it's provenance.

Thank you again for your dedication to the documentation and preservation of 928's...

I'm seeing 16 GTs out of the 90 ROW cars with the XX8 option code. As previously mentioned, the earliest ROW VIN with XX8 is 800191 and it belongs to a S4. The earliest ROW GT VIN with that code is serial number 800579. I don't have information on the actual build date. Hopefully Erkka will see this thread and chime in, he's the real VIN expert.

Some extra ramblings to consider:

Maybe request COA on 800191. the build dates for the parallel VINs may be way off...i.e. 800191 may not have been built the same day or even month as 810191. The bigger markets can get ahead in production. We run into this all the time with the early 10 digit vins... 78 Euro car 1000 was built months before 78 US car 500.

For the 1991 model production numbers it looks like ROW out-paced USA more than 4-1 making it a pretty good chance that 800191 was built before 810182. That's just an estimation though..it is early in the production year and the 4-1 production rate is likely non-linear week by week...they may have pushed out a batch of USA cars early on.

Disclaimer: this could all be completely wrong.

Their cryptic dispatches of information keeps us sucked in like cult followers...brilliant!

Looking at these number of cars made with this option I would expect to see a lot more examples to back up the theory that this is a widebody option code. I am not saying the car didn't have the arches added by Porsche at a later date, just seems highly unlikely that it happened on the production line. It's semantics really as it looks great.

And of course congrats on the purchase

I refer you back to post #15 containing the Certificate of Authenticity from Porsche. Under optional equipment, it says "Wide Body". This certainly suggests it was factory installed when the car was built. Additionally, option code 09991 is "Manufacture from the Exclusive Programme" where custom work like this is performed. The only two option codes we don't have confirmation on are XX8 and 09981. However, we know that Exclusive Program work is often of custom interior nature, and there are many known interior options beginning with 099, so odds are 09981 is not the wide body code. That leaves us with XX8.

I've seen pictures of at least 2 of the ROW cars with the factory wide body GTS flares. One is actually here on Rennlist, an Amethyst Metallic 91GT ex-Japanese car now in Canada. The other was being auctioned in Japan.

Not sure what you mean by "these number of cars made".

The 1650 & 387 are total cars produced that year.

If you look back a few posts, there is 1 US and 90 RoW that list that option.

91 worldwide isn't a whole lot.

I would note, there's a similar known code XC1 - Rear Fender Extension. The master build sheets show 10 ROW 1989 cars with this option code and no US/Canada cars. While not conclusive, this is at least suggestive that XX8 is the "Wide Body" code.

Here's an 89GT with XC1 from a previous thread: https://rennlist.com/forums/928-foru...ung-193cm.html

Wow Jarrod! 10 - 1989's had rear fender extensions that to me look similar to the 964 Turbo! I know that nothing should surprise me anymore with Porsche's "Exclusive Programme" but those XC1 "Rear Fender Extensions" are wild and cool! I hope a few of those have survived!

That of course leaves me counting the XX8 Wide Body optioned cars again and calculating that there is/are:

1 XX8 US/Can 928 GT with the Wide Body option.
16 XX8 ROW 928 GT's with the Wide Body option.
62 XX8 ROW 928 S4's with the Wide Body option.
79 Total XX8's

note: (12 of the earliest 928 GTS's had XX8 on their build sheets but it was redundant as all GTS's were wide body cars.)

The only US/Can GT is: 810182. (121st) was built on 10/8/1990
The first ROW GT is: 800579. (518th) was built on ??/??/????
The first ROW S4 is: 800191. (130th) was built on ??/??/???

Using Droomans 4/1 build ratio (518/4 =129.5) for build dates between ROW and US cars, it is pretty darn close for my GT to be the first GT with the Wide Body option.

I will push forward with my contacts at Porsche, but hopefully Erkka will chime in on this vin dating project.

Thanks again for your information and enthusiasm!

Dave
