CLEVER BOY! ....
I'm in shock you estimate 4,000 VINS in the ETIS system that are unscheduled !!! Let's put that in perspective... we see a couple hundred here on the forums but all those others not posting here. That means Ford is really behind in their builds...and I'm willing to bet most of that is CF and BL.
I built my new Raptor with NO CF or BL and was scheduled 9 days later. (RECENTLY).
Besides the CF and BL lots of BIG dealers with many allocations still not getting their customers build dates. Food for thought. I changed dealers and was scheduled right away.
I don't understand your tool exactly. I put in all my options and my VIN did not pop up. I'm schedule for a build with a VIN but it's not built yet, am I missing something?
Great work on the data collection...very clever.
