1989 Porsche 930 Slantnose Cabriolet M505 Very Low Miles

Porsche 930 Slantnose Cabriolet M505
UPDATE: While I appreciate the kind offers, you should be aware that the highest offer that we have turned down was for $280,000.00. If you are serious about making an offer for this car....your offer needs to exceed that amount (Or Cash offer with Automotive trade).

If you want to just chat about the car in general....please say so in your eBay message. I love talking about the car and Dads collection but actual buyers get priority when it comes to arranging times for phone conversations.


The wife would like to see this go before winter....
Yes....This is the real deal!

This vehicle was ordered and purchased new by my father. It was picked up European delivery and had about 3500 miles put on it as an overseas delivery. After that it was driven fairly infrequently over the years to the present mileage of 5863 miles (which may increase slightly as I take it for some short drives on these increasingly nice days of Spring).
I purchased this car from my father's estate/Automotive dealership called Action Performance about 4 years ago.
My Dad was a renowned collector and was notably one of the earliest people to recognize the potential collectible value of certain vehicles. He was best known in the Corvette, Muscle car and Ferrari circles due to his extensive abilities to see the collectable value of certain vehicles. He was a true enthusiast as he was also one to enjoy the vehicles and to use them respectfully. He cherished the way that they were produced at the factory and carefully preserved their originality. He was truly a master of finding rare factory options and desirable combinations of features. All of his vehicles were professionally maintained and stored in a temperature and humidity-controlled environment. This Porsche 930 Slantnose Cabriolet was no different, having been stored in his personal warehouse with the company of Ferrari Daytonas, numerous C2 Corvettes, a GT40 (P/1059) and various significant Muscle cars.
Since his death in 2007 the collection has been slowly released to the care of others who no doubt recognizes the importance of the vehicles and will cherish them as well. Many of which have become top examples of originality and well documented investments.
In his bid to find the perfect Porsche (The only Porsche that he would ever own), he waited patiently to be able to order what he felt was the most significant Porsche of the era. Since you have read this far, you are probably aware of the rare and exotic nature of the WERKs Slantnose production. More importantly you likely recognize the very small number of these cars that were optioned with the G50 5 speed transmission (only in 1989). This makes this particular Porsche an exceptionally rare example within an infinitesimal number of rare examples.
I won't pretend to know the exact number of 1989 M505 930 G50 Cabriolets are out there.... mostly because the numbers vary from source to source. We can probably agree that the likelihood of seeing another one of this caliber for sale soon....is probably pretty slim. This article puts the number at 28....is that accurate? I honestly don't know. The article is however a nice homage to the cars idiosyncrasies that some find endearing and others find maddening or even dangerous. Love it or hate it, It certainly stands out in a crowd.

Provenance:
Porsche at the time did not keep very good records of the WERKs production vehicles. In fact, there is a very long thread on the Pelican Forums that has been very helpful at tracking the available documents concerning these vehicles. Dad was very good at collecting documents and we are fortunate to have some impressive provenance including his personal correspondence with the Porsche factory concerning his purchase and European delivery. Of Course, included with the purchase will be numerous documents (Including the Certificate of Authenticity) and even some pictures of their trip.
In addition, a picture of this car was featured in an article about Dad in Medical Economics where it was discussed his approach to collecting and the recognition of upcoming values. Dad viewed this car as a driver and did so over the years. Part of the reason that this vehicle was spared many miles was that very shortly after this cars purchase....he bought a 1990 Corvette ZR1 and the combination of being a "Corvette guy" and a coupe, ended up spending more time with the Corvette.
Originality and Revitalization:
At the time of my purchase, the car had not been significantly driven since the time of my father's death in 2007. Basically, it had sat idle for almost 1 decade in a climate/humidity controlled environment. My oldest brother who was the caretaker of the collection had recently passed away so we were unsure exactly when the last time the car had been run. As a mode of precaution, I elected to allow experts revive the car and made no attempts to even start the car. After getting in line for about 1 year, I was able to transport the car to StallTech in Wellman Iowa (if you are not familiar with them....they offer premiere restoration of older Porsche vehicles and are well respected within the Porsche community). It was under their considerable expertise that the car was inspected and "revived". The worklist is included in the photos so you can see what things were done in order to bring the car back to pristine condition.
We were even treated to a surprise when the car first went on the lift and were pleased to find the inspection markings still intact and that the car still has significant coverage of Cosmoline on the undercarriage where it was applied prior to shipping to the United States. Simply a testament of how original and gently this car was used.
The car is absolutely original with the following exceptions. There have been no accidents, Damage or Flaws other than that listed below.
Paint: There were a few very small paint chips that Stalltech expertly repaired on the hood and rear flares. As I recall, these occurred during the European trip during the leg through Scotland.
Tires: I am not sure what brand the original tires were (probably Pirellis, the COA does not specify) but according to the date codes on the current tires....they appear to have been replaced a few months after the European trip with BF Goodrich T/A's. He probably replaced them after the wear from the trip (he was that way). The car now wears brand new set of Toyo Proxes R888s (roughly 3 years old at the time of this writing). The "original" set of tires is included with the sale should the new owner prefer a period set of tires on the car.
Mods: There has been a small but significant (and easily reversible) modification made to the fuse system. Basically, a modern fuse hack has been applied to the fuses that run the fuel pumps. This has made startups considerably 100% reliable in the humid Iowa weather.
Starting Module: For the sake of reliability, the original CDI ignition module was rebuilt to factory specs.
Any questions about the cars "revival" can be discussed with the staff of StallTech. I am sure that they supply ample details and I am sure would be glad to assist in any verification inspections if requested.
The fine print:
Inspection: We encourage a personal inspection before purchase and will do our best to accommodate your schedule.
VIN: WP0EB0936KS070543
