I received a text from the sales rep later that afternoon that I could purchase the black Z71! Finally a bit of good news. VINview shows a delivery date of 8/8. What is odd is that it was built AFTER the midnight blue Z71. The midnight blue had a 3800 code as of 6/23 then moved to MID lot on 6/24. I was not able to get the event history for the black one but its VIN is -360XXX. The VIN for the midnight blue is -339XXX.
I am assuming some chips were delivered to the Arlington plant during the time that the black one was still on the assembly line and they were able to build it close to completion. This is all speculation but it kind of makes sense to me. So now the trucks sitting in MID lot were moved there due to missing parts/chips. I believe they have to be moved back to the Arlington plant for the missing parts to be installed. Or could those parts be installed on the lot?
The components are delivered just-in-time for production, so if there is a shortage, whatever was built that week goes to storage, but the line keeps running. That's why you see more trucks from March/April/May in storage waiting on chips, and more trucks going to dealers in June/July. Just depends on how much of the component orders are fulfilled as the trucks move down the line.
