My understanding, and please more knowledgeable folk correct me if wrong, is that they basically only get a small fee for handling a motability ‘sale’ whereas there is more margin in normal sales and bonuses and all that lark. So we get treated like second class citizens by some dealers as a result as there is less money in it for them.
Some places are great, others just plain ignore you if they make the assumption (easily done with me and no doubt many others as I either walk with a stick or at times use a wheelchair) that you are motability. :/.
Fwippers swooped in (an aforementioned more knowledgeable person) and answered the question as I was typing, but I will post regardless :).
