You can put in a Factory Motability order BEFORE your lease window opens. If the vehicle is removed before your window opens, motability will accept and add the vehicle to your lease. It used to happen a couple of years ago as some cars were on a 13 month waiting list post covid.
But you need the motability salesman to be on your side.
It should not be like this, but choosing a motability vehicle should NOT be a lottery.
Wondering if your chosen vehicle is gonna be there when your window opens.
