[WONT]New Year Model replaces existing Year Model Automatically

[-root]

I feel like the "new year model" should automatically replace the existing year model throughout the game.

Whenever a new vehicle is redesigned, you have to go through and set it all up again. It should do it automatically.

Maintain "New Trim" for a special edition or different version of the car. I think the "new year model" should be a natural upgrade of what you are doing.

The computer should maintain the same percentage difference between build cost and sell cost for the new vehicle as you had it set for the old.
