With NHS fleet salary sacrifice schemes, you can adjust the mileage allowance and the monthly payment increases accordingly. It’s quite flexible depending on how much you actually drive. I think Motability could do something similar. For example, allowing higher mileage in exchange for a higher Advance Payment. That way people who genuinely need to drive more have an option, rather than everyone being on the same limit. It would make the scheme feel a lot more flexible and fair to different circumstances.
