It’s fine saying people don’t want to wait if you already have a motability vehicle and can just keep it.
But if like me it’s your first car, I needed a more suitable and more reliable car so myself and my wife could leave the house when we wanted.
The thought of waiting 6 months not being able to do what we want when we wanted is a scary one.
My wife suffers anxiety with her epilepsy so won’t go in hospital transport, I can’t get in and out of an uber style cab as it’s too low and like me my wife can’t walk far, we couldn’t make it even to our nearest bus stop.
So we needed a car as soon as possible for our mental health.
