I find it best to speak to dealer. Explaining if price drops Q1 you wish it at lower price even if it means cancelling and re ordering. I did same just this last quarter I ordered Kuga ST Line X in final couple days of Q3, however price dropped Q4. So my dealer re-ordered at the reduced price I have had confirmation from motability of order at lower price.
