I wish there was a way to estimate an accurate prodution/delivery time. Ford/UPS (yes, brown truck guys) have been trying to work on it for years. Automobiles are not boxes or packages. Shit happens during transit that Ford/UPS can not predict (flat tires, dead batteries, theft, vandalism, someone misloading or misshipped, derailments, floods, lack of railcars, lack of locomotive crews, hail damage, etc)
And that is only part of the puzzle. You also have production hold, issues, quality holds, return to plant, and vendor part delays on the manufacturing side. Then the delivery side full unloading facility, off site storage, lost keys, out of gas, lack of transports to carry vehicles (especially with the Raptor being so large there are only certian types of trailers that can carry them), dealer closed, accidents, theft from dealer lot, etc.
Ford/UPS/Dealers (most) do everything in their power to get the vehicles to their customers. It is a frustrating system to navigate but it works, and it is improving every year. Average transit times are getting closer to the ideal 96 hours.
I will help out as much as I can in understanding this system. And I know Randy will go above and beyond for his customers and forum members.
