Motability are not interested in the problem. That is why they contract out Dlm insurance and RAC cover.
They just point the customer to the correct agency. How DLM, or Eurocar operates, they do not care.
Best to do a complete video of the exterior, and interior of the car and the mileage, just to cover yourself. Include the positions of the 4 wheels and tyre valves to prove the car has never moved.
Do it to cover yourself in case anything happens to the car. You have that recording on that date.
