I’ve ordered our last 3 Motability cars before our 3 month order window opens – in fact one was over 2 months early. You can only do this as a ‘gentleman’s agreement’ with a willing dealer, as they take a risk that the car may be removed from the scheme by the time that your 3 month order window opens. Whilst what shows on the Motability system as an order isn’t actually an order at all, and is only admin, this can only be done when your official 3 month order window opens. You are then committed to the AP at that time, not the AP at the time that the dealer kindly ordered early for you. So ordering early gets you the car quicker, but doesn’t protect you against an AP increase.
