I wonder if that comment “may charge a cancellation fee” is just to deter too many people from doing it? I can recall quite a lot of examples of forum members cancelling orders over the years. One or two had some initial hassle getting deposits back (but always did in the end, so I don’t think they are truly non-refundable) but never have I heard of anyone incurring a cancellation fee. Surely for that to stand up in law you’d have to have signed a legally binding contract that specifies what such a cancellation fee would be? I don’t ever recall signing such a contract with any of our Motability car orders.
