Strosek Ultra

That is a bargain price. The Minerva sister car is for sale in Germany for appr. $135k.

..'79 sister to a '88?,
That's more like 2nd cousins over here.

Strosek Ultra

No, the sister car to William´s and Rob Edward´s car named Minerva.

Missing the surround on the radio. 20k off for that...

S4 slots are not finished beyond the color of the aluminum. Some folks put black to hide staining from brake dust, but that is an owner modification. It's a chore keeping the area behind the slots clean and bright, since airflow draws the brake pad dust out through there. But that's how they were originally.

^^^ agree ... never seen black paint, and all the reference pics of low milers I have show originals as all over anodised.

OTR18WHEELER

Well, I have a two sets of OEM slots that are very rare then.

Looks completely correct for the mileage.

09 at the end is about to roll to the 10, and 97xx is getting close enough to 10000 that its starting to roll.

My '87 is currently doing the same at 199200km - all lined up perfectly before then.

Plastic drive gear in the mechanical odo pre-'89. They all fail. They have all failed already. Or they are one trip odometer reset away from failing.

I consider any pre-'89 to be TMU (Total Mileage Unknown) until I see it with my own eyes.

I bought a 60k km cluster from a Japanese S4 which got parted out years earlier. The plastic drive gear in it was non-existent.. just fragments left.

On the flip side - my current 87 S4 from the UK has a completely working original cluster, and documented mileage to support.

Either the plastic used by Porsche was highly variable in quality (possibly multiple sources?) or something environmental has a major impact on gear longevity too.

Regardless, Dave's spot on - they have a finite lifetime, and the failure rate at 20 years old is very high, which means a lot either don't work, or have been apart and should only be trusted with adequate documentation.

It's a VDO-sourced instrument. AFAIK all VDO odometers from that era suffer the same fate (Porsche, VW, etc.) They seem to fail, mostly it seems, as a result of resetting the trip odometer when the car is rolling at speed.

I have always assumed that it's temperature and heat-cycling that kills the plastic - same as most other stuff that degrades for reasons not primary related to use.

Cosmo Kramer

I think the issue was Porsche put a grease on the VDO gear that wasn't compatible with the plastic and caused them to fail.

worf928

That's quite plausible. VW must have used the same grease.

Nevertheless, I still think it extremely likely that Porsche (and VW) didn't do anything to the odometers. They got a box of them from VDO, stuck them on a shelf, and pulled them out one at a time as they assembled cars. And thus, grease or no grease VDO is to blame.
