The cost of these vehicles make them virtually unsellable. These are the ones that they have kept, there will be more that get scrapped/ scavanged for other projects.
But i think its nice that they have kept some of them... I suppose it instills a sense of heritage. They also have an example of every M car produced in the garage.
i have just noticed that the M8 appears to have had some work done to it since the first pictures of it were released. It used to have a two piece front side window, with only a small piece dropping down. It now has a standard door and window...
