They're all interesting in their own way. I've never had a Laverda, I toy with the idea but current prices have pushed me into other Italian bikes with less agricultural performance. If I were buying from this group, the green 1200 is strangely attractive... probably because of its originality.
Another interesting bike is in the background of the green 1200 advert - a metallic blue Darmah. These were a small batch (13 bikes if I remember correctly) that were maneuvered into the US by labeling them as 1982 models when in fact they were made in 1983. The importer at that time was in Texas and I think sold mostly the VM diesel engines that were Ducatis meager bread and butter in the period just before Cagiva took over.
