As I said previously I do not want to get in to an argument or spend the rest of my life posting replies. Simply call the purchase team at motability operations on 0300 0379899 and ask them. They may be some misunderstanding with regard to purchasing your car before the end of lease such as when you are half way through the lease or the person on the phone was not from the purchasing team and was misinformed.
Once you have called them Dave would you mind putting your findings down in this topic page..
thanks
