Well....
They have a lot of heavy , hard to sell trucks and cars.
The military needs trucks , so do forest rangers , border patroll ,FBI, DEA etc.
The auto manufacturers need a deal.
Why not buy a big part of the inventory?
And attempt to make a sellable product next year.
I once heard that criminals soon learn the look of all the FBI cars in their region because there are only just so many in a town and the government buys a lot of the same models.
If they use my idea the criminals might start to duck whenever they see a heavy car.
