It stands for "freight on boxcar"
Cars whereTHEN and still are TODAY usually shipped by railway to a depot at a desination close to the various states to a depot and unloaded, then shipped from that depot to the selling dealership by truck.
YES, It is still done that way today.
There is a destination fee that goes along with it also on every invoice that will match this FOB.
The only way a car or truck did not have this is if it was picked up by the salesperson or buyer at the assembly plant.
Some special sales cars and trucks did not get that.
Some where shipped by sea also which has a different destination designation.
Hope this helps you all.

(yes you can still go tour and pick up your new car in person if you wish today btw!)
