Possibly if you pay for it yourself (no harm in asking), but Motability have an odd policy that if you get to the point that you need adaptations they let you order a brand new car. We had an odd situation years ago where we had a 12 month old car, my wife then needed push-pull controls, we said we were happy with the car and were happy to have them fitted, but they said we should order a brand new car. We ordered exactly the same car again and they paid for the adaptations 🤔
