I've ordered my Astra 12th April, delivery date is in August - Sept. The dealer said that it might be a model my2017, but since the contract has been made for 2016.5 I think I must get all the stuff that are on the contract and for the same price which is on the contract. It is believed that prices for the my2017 will be changed (matrix will be more expensive and 17inch alloys), but I think that mustn't effect my order and the contract. Any info on that? And on the changes my2017 model brings?
