Hi donald
We have had a few enquiries similar to yours. The consensus was that you should contact Motability and explain your circumstances and that you were going to appeal.
Some members informed us that they were allowed to keep their car whilst they applied for a Mandatory Reconsideration, if they failed at MR to get the enhanced mobility, then they had to give the car back whilst they appealed.
