Well I researched this a little and here is the real scoop. Still a fantastic collection of cars!
Old Cars Weekly just tracked down the story behind the story, and the real explanation is almost as good as the hoax. What we are actually seeing in those pictures is the collection of an automobile dealer who over the years has added many vehicles that caught his fancy. He just drove them to the barn and parked them there, presumably waiting until he decided what to do with the lot of them next. About a year ago he sent in a photographer to document the collection, and those pics are the ones circulating the internet, helping to create and sustain this myth. So now you know the truth behind the Great Portugal Barn Find, and you all can stop sending us tips to cover it.
