in august 5th 1968 no 1969 models would have been at the dealership.
The dealers were selling all the 68 models they had in stock.
They couldn't take any orders for 68 models to be built. ................. ( You mean 69s)?
If a customer wanted something they would have to find out if other dealers might have it.
The cars built in august and early/mid september were all located on parking lots close to the production plants.
Just within the last week before the official release they started delivering them to the dealers.
