I was designing an expensive car in the car design dialog. I checked all features available and marked the car (Sedan EX) up to 55%. I finally reach the expensive threshold with $47,042. When the car reach the showroom it has a price of $43,042 and now in the mid range. I rechecked the design dialog for that car and it still shows $47,042. I thought the design dialog adjust the design price to common/rarity of car upgrades. So why the different prices?
Attached images of the two dialogs. As you can see the tooltip from the showroom does not indicate any missing car upgrades so they should be the same price.
