... Last time I have met with Moravian veteránistom , which gave the KDF chassis boxes of Spartacus.
For many years go by Czech roads and lately even veteran events this interesting car.
KdF 1942 III. Laminated body is built on the chassis of a military vehicle KdF 82 in 1942 , but has no plate or label. It is therefore a question of who built this car.
The current owner, Mr. Joseph Foundling plays with the question of whether it is one of the first eccentric cars, which in the sixties built on the chassis VW KdF - now famous designer Luigi Colani.
KdF 1942 II . My personal opinion is that it is a clever construction of Czech amateur who is this car built in the early sixties to your liking and for pleasure."
