This would be a great car for anyone looking for an automatic.

Wow. I guess he didn’t like it.

My 87 is going to go soon, I'm no celebrity but Venice Blue with clubs and no rubs. I have been swayed by another Porsche and can't resist. Trying to figure out where to sell it. That first bid was a doozy for the Martin car.

no doubt

Good looking car. Same motor/trans as my 88 S4. Notice that he doesn't know to list his 4 wheel steering Weissach axle, though. Even shows it in his undercarriage picture, but fails to highlight it as if he doesn't know what his car has.

Same again for his Front and Rear OEM Stabilizer Bars. He also misses that he has an adjustable left foot-rest for the driver.

I hope that he scores big, but he left money on the table by leaving out key features.

so i had a question about this, on my 87 there is no option code on the trunk sticker for the weissach axle. but on the window sticker i think it shows up there as "widened track rear axle" under standard equipment. this always led me to the impression that the weissach axle was standard on 928s. is this not true? any more info to clarify would be great, thanks!

Every 928 was a Weissach rear axle - that is one of the defining characteristics of a 928, and not an option. It is part of it's DNA. Nobody ever lists that in a for sale ad. At least that I've ever seen. Also, a Weissach is not the same as a widened rear axle. The GTS pushed out the rears, although I do not know if that was just tires or a wider track at the axle.

KM had it for sale before BaT at $53K? I haven't done the research yet, but I believe that would be a record for an S4 auto on BaT if it goes to that level.

"The GTS pushed out the rears, although I do not know if that was just tires or a wider track at the axle." Ed, The GTS has spacers between the axle and the wheel. As I recall, they are about 40mm (haven't measured one in 7-8 years!). So, the centerline of the tires is about 3" wider on the stock GTS set up than it is on the stock S4/GT suspension.

thanks, that's what I always thought about the weissach. The widened rear track, still less so. My s4 without the rear flares lists the widened rear axle, so I guess still dont know what that refers to.

Based upon what Gary said, and my additional research, the widened rear axle option appears to just be a spacer package. My 85 has that too, as did my 86.5.

I guess you missed the part where he said it was a (the one and only, apparently) “S/4 GT automatic”

no doubt

4-wheel-steering Weissach rear axle is for a fact on all S4 models and at least 200+ Weissach edition 1982 928s.

Leaving that feature out of a spec sheet or ad is like omitting 4 Wheel Drive when selling your Land Rover even though they all have it. While 928 aficionados know that 928 models have 4 wheel steering, many potential buyers will not know that fact. As a seller, it's your duty to enlighten them to every advantage that your 928 has.

People will claim that you don't have to mention the obvious features of your car in an ad, but every person who says that simply didn't know to say it. That's just excuse-making.

Tell your audience what your car has, especially if it is a significant feature like 4 Wheel Steering or 4 Wheel Drive or Left Hand Drive or Automatic or manual-shift, etc.

Correct - Option Code 415-Wider Rear Track is 21mm spacers on the rear wheels with longer studs. I'm not sure what year this option started with, maybe with the S cars. My 84 Euro has this option.

As said in previous posts, all 928s, from the very first to the very last, have the "Weissach" rear suspension. It is not a true 4-wheel steering system where the wheels articulate when you turn the steering wheel. It is simply a geometric configuration of the control arms and bushings that cause slight toe-in to reduce lift throttle oversteer. It was innovative at the time of the first 928, but lots of cars today with independent rear suspension deploy a similar concept.
