Sadly, this is yet another of countless examples on this forum where people trust that because a car shows as ‘ordered’ on the Motability system it has been. It is always essential to get a manufacturer tracker number from a dealer so that you can check yourself that the car has actually been ordered.
Very often, dealerships will input the details on the Motability system (which makes it show that it’s been ordered) when in reality they cannot place the order until a month (or several months) later when a manufacturer build slot opens up. They will never tell you this unless you specifically ask.
If a dealership won’t give you a tracker number that you can check yourself with the manufacturer, you can rest assured that the car hasn’t been ordered.
