We see the term "bayed" used a couple of ways but they are not interchangeable. In this case the 4B00 is bayed for shipping. Meaning that it has been turned over to Allied. The key is that it has been invoiced to dealer (4150) and they won't do that until it is ready to be moved to the Allied lot. If it was "bayed" for QC or repair as can be the case the car would still be at 3800.
This is also referred to as "bayed" because it is moved in to one of the repair bays at the end of the assembly line. This is more appropriately held for QC.
You should be good to go.
