If you’re on Facebook hunt out the ‘Motability Advice and Special Offers Group’, they have a number of dealers who may have something you want available sooner rather than later. I’d give up with whatever order you think you have but check with Motability if you’ve an order in progress for something and, if so, what. Then see if something is coming up sooner than that..
Good luck.
