Welcome!
I would call motability and ask their advice. They are real helpful. I’m in th position to change my car (5 years with a Kia Sportage) and a lot of the cars I looked at have come off the scheme the car I currently have isn’t even on it. I spoke to motability about options they said the Dacia duster might be an alternative. Now I’m not a badge bothered but that wouldn’t suit my needs for 2 wheelchairs one being powered in the boot, so surprised they said about that. Though they did say what about the Peugeot. This makes me think that the lead time may not be as long in Peugeot. I have driven one but hated the steering wheel. I have bad hands and I just couldn’t find it comfortable so a longer journey would be agony.
Motability were helpful and tried their best as they know there’s an issue with less times and cars especially suv going off scheme.
give the dealer a call just to see any update or even try another garage.
I would give them a call and ask what would they suggest. I spoke to a lovely lady that day who went out of her way to help me. See if they can help and good luck with whatever new car you choose
