Yes, it’s annoying when the price drops massively, but equally, it could, as many have found go the other way, oddly people are never unhappy then!.
Those who have already ordered may breath a sigh of relief when prices go up, but those who were considering the car, or couldn’t order before the price rise, will clearly be unhappy.
As an aside, one thing that really irritates me each quarter change is when some people post gloating that that they ordered before a price rise. I take the opposite view. I think it’s sad when cars suddenly become out of reach for customers who would have liked one. There are quite a few members of this forum who struggle to raise even modest AP’s and I really feel for them when this happens.
