I wonder if that is a “former” German military car in the picture?
When going to watch a volcanic eruption with the extremely abrasive volcanic ash falling, I always try to go in someone else vehicle. Or I stay at home and drink Dos Equis (IPA really)
I’m guessing you are referring to the review view of the vehicle in the center as the “former German car.” It is a US Army Dodge WC-56 or WC-57, series 4x4, 3/4 ton, Command Car. See this Wikipedia article and photographs:

The left hand vehicle is, obviously, the good old Army jeep.
