The reason for the lack of knowledge in customer service or the missing documentation in the VW system is likely that these cars were never intended for production or series manufacturing, but were instead designated as so-called "KFA cars." The meaning of KFA remains unclear till date - VW employees explained them as follows:
KFA cars are simply assigned a "project number" until it's clear whether the model will be built in a series or not!

Once this decision has been made by VW management, there are two possibilities:

1. The cars go into series production and are therefore entered into the standard VW systems/databases,
   such as KVS or ELSA, to ensure compliance with various VW procedures and fundamentals. 

2. The cars are not built by agreement within the group, which means the immediate scrapping of the prototypes and parts with VINs or serial numbers – a standard procedure! Parts without such numbers, on the other hand, often find their way from "disposal companies" to local tuning enthusiasts, collectors, or other willing buyers!
