If you look closely, you'll the see above photo has 2 pieces of lumbar stacked on top of each other , both sides of the container, from the front to the back. Doesn't look safe to me.
Photos from http://svammelsurium.blogg.se/ becuase if I recall correctly, that blogger works at a recieving location where collector cars come into Sweden Marten (http://svammelsurium.blogg.se/) tells me
Since the customs about a year ago raised their costs excessively for goods from the US, people shipped cars via the Netherlands and paid only 6% fees, but now they raised the fees to 20%, so what is done now is to take the cars to France which has a regular fee of ony 5% on the custom value. The reason for taking a midway landing is that when the car is brought here its suddenly a European car, and then taken into Sweden with no charges at all!
