Some people obviously sympathise more with the dealer than with you, the person who’s car it is, choice it is, money it is, it’s a lot of money over 3 years plus whatever AP and I would not stick with a car I wasn’t happy with for whatever reason and pay nearly ten grand, if the people that disagree are willing to pay it for you then I suppose they can have a say, otherwise your choice and choose what you like, call dealer and change the colour and if they refuse (old story of they have the order and don’t care now) then cancel and report them to Motability and go elsewhere mate.
