One of the "Deehatsus" has a pair of stickers on the windscreen in support of agriculture. I think they're from around 2000, when farmers went on various demonstrations around Belgium. But looking at the cars themselves, it's clear this not a car graveyard from the olden days when Beetles were part of the daily traffic. This is only from 15-20 years ago, when Beetles were already in the hands of enthousiasts (collectors, customizers, autocrossers). IMHO, it's really surprsising to see a place like this already abandoned and explored as if it was some ancient relic.
