Ordered my Dynamic in September and recently received details of my build date and a scheduled delivery date for January 2012. Went to the Dealer today to agree the Part-Ex for my current car, only to learn they have failed to add the Park Assist to my build order! As a build date has now been given they are unsure they can amend this, without the delivery date being affected. Gutted! Do i accept the car in January without Park Assist, or request they amend the order, and defer my delivery? It's a shame as until now my dealer has been really good.
