In the actual issue of the classic car magazine "Oldtimer Markt" there is a big story of this barn, of which a plenty of stories, legends and mysteries are going around.

The story, that someone has fould all these cars inside it, when he had bought a house and the whole areal, is wrong, just one of these "urban legends".

The cars are owned by an old used-car-dealer and classic-car-collector in Lissabon, who picked them up in the years after the revolution in 1974. He got them very cheap, because the people have thought, that now the socialism will start in Portugal and that their big "capitalistic" cars could cause problems. Now he have decided to sell some of them. His son starts to offern them.

Something similar in Nevada:
