The wheelchair didn’t come with our last car, a specialist mobilty supplier (https://www.bewickmobility.co.uk) delivered it direct to our house a couple of days after. Ask Motability who can probably add it to your order from their end.
Same thing here – mine was delivered to the house a week after we got the car
