PET doesn't give any differences between '90 and '91 MY. It could be US thing that almost all '91 got D90's as they were no charge option in both years and thus are very common especially in '91 MY. Possibly because dealers ordered cars with M400 option thinking its easier to sell new cars with latest look wheels. There are at least few '91 S4 in Registry which have M400 code.

Having code separately listed usually means its extra option or at least possibly to leave it out. Leaving it out meant M347 flats with RDK. Does anyone have this code in '90 or '91 S4? If not it would mean they were standard wheels.

Its likely D90 cost extra in Europe. Almost everything was extra in ROW cars until last 6 or 7 MY's. Its likely that if D90 didn't cost anything in ROW markets either Porsche would not have bothered making flats anymore. In German sites like Mobile.de and others its impossible to say what wheels those cars had as Germans seem to change wheels more often than any other people. Almost all cars have non standard wheels making it impossible to say what wheels standard bare bones S4 had when they were new based on used cars on sale today .

Our '91 S4 does not have either wheel option code listed. I bought it with aftermarket turbo twist wheels on it. So whatever the stock S4 wheel was in 1991, I would say our car had stock wheels originally. I might be looking for a set of D-90 wheels though. Are they pretty expensive due to limited availability??

Dealer website pictures show the electronic odo at 3915 miles and the AT shifter, and the price. $33K for a 91 S4, even a super low mile creampuff, is steep.

D90 should be very easy and cheap to find as so many owners have changed to aftermarket wheels. They aren't exactly hot item like Club Sport wheels. RDK sensors will not work in many of them though.

I really like the color combo of this 928...BUT....the price is way steep for a 928 that probably needs a mountain of restoration for all the little dried out rubber bits from a lack of use....if someone wanted to make it a reliable driver...it would take quite a bit of work to be 100%....at least thats what I would try to sell the dealer to lower the price!

My guess is it is probably worth $25K....

Remember, it's a 91 - the best of the best non-GTS models. It's worth what somebody wants to pay. And if you consider what a GTS with 39k miles would cost, I don't think the asking price is high at all. In fact, I think it's a bargain for a practically new 928!

Nicole is right. Never remenber it's the best or one of the best GT car ever built

hi all,

From France point of view, ie: in France there was not a local subsidiary but a retailer (an importer). It used to include equipment in the car in order to be more valued. I think, for our case, all 928 S4 and GT post 89, ie from '90 MY , had D90 wheels. But it seems that german S4 '90 MY had been equiped with flat dish until the end of the stock, and then standard wheel became D90 after. For the GT, D90 were standard equipment

That would explain that M400 and M397 are so rare because it concerned very little part of the production.

anyone run a carfax to verify mileage? I have my doubts.

VehiGAZ

That car is in New York - that's definitely Jericho Turnpike in the background of the pictures. I passed by that place on the way to buy my '89 GT.

Very pretty car, but can you really believe that mileage? It probably needs all new gaskets, hoses, and belts. Anyone run Carfax on it yet? Speaking of which, have there been cases of people altering the mileage on these digital/computer odometers?

Vilhuer

Yes and no. I haven't heard about cases where existing odo numbers were changed even though its possible with enough knowledge about how number is stored in dash memory. There have been many cases where odo hasn't shown correct numbers because complete dash or just circuit board were changed from different 928. Also its possible to get low numbers by changing completely new circuit into dash. It allows numbers to be set manually until few 100 miles are driven. If this is not done during that time numbers just keep on going up like car was new and thus whatever miles were in original dash are lost.

Today's values that are placed on ultra low mileage cars that aren't 928 standouts clearly destined to be collectible ('95 GTS 5-speeds, & early production '78's) is debatable. Whether a '91 S4 in like-new condition is one of these is speculation and will likely be defined by what it sells for. If this S4 is regarded as a classic or collectible to a prospective buyer, it's worth every penny, IMO (assuming the mileage is legit).
On another note, I often see comments about 'dried out rubber' being a characteristic/drawback of a car that has ultra low mileage. One has to assume that a preserved car like this has sat idle for many years in climate controlled storage. Isn't the 'dried out/cracked rubber' phenom. a thing of the past, or is it common for a time capsule like this (or Kermit) to have dried out rubber parts/gaskets. I don't see it.
I ask this because it's my guess that a car kept in a climate controlled environment with minimal exposure to the elements like UV, rain, salt, heat and temperature extremes would have better preserved rubber, inside & out.
My car has relatively low mileage (45k) and stays out of the elements. I have no leaks whatsoever (except for having needed an o-ring overhaul in my AC system) and all of my 'rubber bits' do not show their age at all. They're in much better shape than my newer Ford Explorer daily driver, particularly those that are exposed to UV.
I've heard about gasket shrinkage in an engine that is hardly ever brought up to operating temp. People used to put their cars on blocks for extended periods of time because the tires would flat-spot and wouldn't recover, and bearings could distort over time. They also changed their oil every 3k miles.
Hasn't new technology & formulations of gaskets, hoses, belts made these concerns a thing of the past?
Chuck?

I like the color, but does it strike anyone as odd that a like-new GT [edit got it mixed up -- right it is an auto therefore S4] ends up at this kind of corner-lot dealer. A car with this kind of mileage is usually snapped up by a higher end operation.

JPTL

I wonder if those are the original tires. They aren't Comp T/A's which were OEM for many '91 MY. Looks like a non-tape weight on the wheel rim.
If they aren't original, why would somebody change them at less than 4k if the car is going to be a time capsule?
