I have the majority of these vehicles (I have all but just under 90 or so cars in the game) but the Transit FE was the only eligible one I could use from my garage and the Merc racing truck was the only one available to purchase for some reason.
The race truck is the only "native" B class car in that list, which is why it's the only one you're able to purchase. If you upgrade any of the others to B class you should be able to use them.
