The main topic was, that it was under a bridge of the town-autobahn, which may have been damaged by that fire.
This fire, which started in a garage of a towing company, destroyed less cars than the fire in Liverpool, but, as it was to read in the medias, some classic cars were destroyed, too, for example one classic Ferrari.
