They are all but exhausted in the government surplus marketplaces..
The production numbers made the majority of the models M1008 more available when they were being sold off.
The models like the M1031 and M1028A2 always brought a premium as we have sceen in the past where I asked for guesses on final price I think it was a M1028A2 in a thread on the P forum.
The M1031 and M1028A2 had or at least were more likely to have the fig 8 pattern NP205 transfer cases.
But to be fair for anyone that goes to the expence in time to go search for it I might have deleted the thread.
