It is my fault, sadly. Current lease started 2019. So 5yrs is 2024. Numbers have become slippery as I have aged.
Well if next year is 5 years then you’ve done nothing wrong, as that’s the maximum lease period allowed. If your financial position doesn’t allow you to leave the scheme and buy something more suitable, is it worth seeing if there’s a car with the one thing that cannot be worked around (rear door clearance) and then if it doesn’t have a power tailgate or power seat as standard see if Motability will pay for adaptations?
