Short answerA Canadian seller offered a yellow slant-nose Porsche on eBay Motors with a $21,000,000 starting bid, calling it a lost “P 911T Prototype” linked to the 1963 Frankfurt 901. Its chassis number, 9111120162, decodes as a production 1971 911 T coupé bodied by Karmann, and its Porsche Certificate of Authenticity also says 1971 911 T. No published factory record supports the prototype claim.

This is the story the domain was known for. For several years porscheprototype.com promoted a single car as a lost Porsche prototype worth tens of millions. The pages were long, emotional and full of real Porsche history used in the wrong places. This file keeps the claim and the record side by side, and treats the former owner with the respect any enthusiast deserves.
What did the listing claim?
The listing claimed the car was a one-off “P 911T Prototype 911”, connected to the yellow 901 shown at Frankfurt in 1963 and to a secret “901 235 3000 series”. The website around it called the car a “National Treasure” and said Porsche and Volkswagen had hidden its history.
The evidence offered on the listing and site was:
- A front tub tag reading “P 911T Prototype 911”
- A hand-fabricated exhaust that dragged on the ground
- A brake pedal assembly with a machined cam that increases braking leverage
- Microfiche documents found inside the car
- Slant-nose bodywork, louvred wings and an open top
- Conflicting paperwork: an Ontario registration as a 1986 911 T and a Porsche Certificate of Authenticity for a 1971 911 T
What does chassis 9111120162 say?
Chassis 9111120162 says 1971 Porsche 911 T, coupé body built by Karmann, serial 0162. Porsche’s ten-digit format from 1970 to 1979 encodes each part of that directly.
| Digits | Value | Meaning |
|---|---|---|
| 1–3 | 911 | Type 911 |
| 4 | 1 | Model year 1971 |
| 5 | 1 | Variant 911 T |
| 6 | 2 | Coupé body built by Karmann |
| 7–10 | 0162 | Serial number |
Cars in the same sequence are ordinary 1971 911 T Karmann coupés that change hands on the classic market; chassis 9111121137, for example, sold as exactly that. The Certificate of Authenticity for the yellow car agrees with its number. Try it on the Porsche VIN decoder. To confirm a number on the car itself, see where to find the VIN on a Porsche.
Could a tub tag or special parts prove it was a prototype?
No. A tag or part can be moved, copied or fitted later, so it cannot outweigh the chassis stamping and the factory record. Early-911 specialist Dennis Frick, who restored prototype 13327, commented that the car had some very early parts, such as a pedal cluster and heat exchangers, and that its description of the pedals as “mechanical power braking” was accurate. Early parts on a later car show where parts came from, not where the body was born.
What about the slant nose?
The slant nose is the strongest evidence against a 1960s origin. Porsche’s factory Flachbau body was a 1980s special order, and aftermarket shops converted many earlier 911s to the look. A 1971 car registered as a 1986 with slant-nose panels fits a later conversion. The factory slant nose versus conversion guide shows how to tell them apart.
How did the press cover it?
The press treated the listing as a curiosity. Carscoops called it one of the strangest listings on eBay Motors and noted the dedicated website’s “Shocking Secret Myth” and “Porsche 911 Conspiracy” sections. The Gentleman Racer covered an earlier 2013 relisting, and sites in France, Poland and Greece picked up the story again in later years. The attention is why links to this domain still exist.
What would it take to prove a prototype claim?
Proving a prototype claim would take a factory record that ties the body shell to a prototype programme, plus physical evidence that matches it. In practice that means:
- A Kardex or Porsche Production Specification showing a non-production build
- A chassis number from a documented prototype range, such as 13321–13360 for the 901
- Period photographs or archive documents of that exact car
- Inspection by a marque specialist of stampings, welds and body structure
The yellow car met none of these on the public record. That is the whole finding, and it is the method used on every page of this archive. The documented 901 prototypes are listed on the 901 prototype chassis page.
Frequently asked questions
Was the $21 million Porsche 911 T prototype real?
The car was real, but the prototype claim is not supported by any published record. Its chassis number decodes as a production 1971 911 T Karmann coupé, and its Certificate of Authenticity lists a 1971 911 T.
Why did the car look different from a 1971 911?
It wore slant-nose (Flachbau) bodywork with louvred wings and was an open-top car. Slant-nose styling dates from the 1980s and was widely copied by conversion shops on older 911s.
Why was it registered as a 1986 in Ontario?
The listing stated an Ontario registration as a 1986 911 T while the Certificate of Authenticity said 1971. Registration years can change after rebuilds or re-registration; the factory record and chassis number are the stronger evidence.
Did the car sell?
There is no public record of a sale. The seller relisted it several times from about 2009, and the associated website stayed online until the domain lapsed.
