I would think the upgrade costs and repair costs change when the price changes, because the former are calculated from the latter. But I have seen strange things happen in the game before, so it would not surprise me if somehow this is not the case for everyone.

Maybe ParadiseLover can give his view on how the upgrade/repair costs come to be?
