Going out on a limb here, but I predict the overall rise in the price of Mokes will slow down and begin level out after about five years of increasing value and renewed interest in the Moke. Although I can't see a burst but a rather a slow leak.
This specimen of a Stainless Steel Moke was spotted in transit in a Melbourne transport depot. Not a lot of them around so very rare to see one these day and this one looks like it is surviving well.
