This was a safe spot and the Nazis would never find it. But as time passes, nature itself has touched these cars and they do not look in their best shape now.
They are covered in dust and has many rust damage. The biggest sadness is that they are not used for a very long time and have lost their glory of being useful.
To hide this kind of treasure may have looked simple in that time when the Nazis only wanted them to take some parts and create their own machines, but today they really are a treasure. They keep a whole history and a desperate calling for help. At least they survived that horrible time.
