I think what likely happens is some dealers will place orders without necessarily having confirmed buyers, which in the current climate is prob low risk as unlikely they will be sat on the forecourt that long.
Other dealers will possibly order only when ordered by customer, or even if they have sold the batch they ordered without buyers. This method would incur the biggest delays as the customer starts counting from order placement.
My order was from a batch that had already been ordered from the dealer, I could have any as long as it was LR exclusive in white ? Not my first choice colour but risked waiting longer so compromised.
