Hey, When you got 100 hidden packages and it said special Vehicle delivered to Fort Baxter Air Base That was not the Hunter/Apache it was the ultimate Vehicle. It says so in my Strategy guide. It says its the best Vehicle in the game
That is the ultimate vehicle. That's why it was in the odd jobs section of that strategy guide, because you can do the vigilante mission with the hunter. It even says so in that strategy guide that the hint will be given somewhere in the guide, and if you look where they have all the hidden packages and the prizes that you get for it, it'll say "100 packages ---- Ultimate Vehicle."
