The problem is that everything in a brochure or options list is not not necessarily available at the time of production as the car comes down the production line. And it is established in law (Johnson V HWM) that it is not always possible to supply a car exactly to the ordered spec. However, if any of the options fitted are dependent on other options not fitted then you have a case either to reject the car or for a refund of the cost of the options rendered useless.
