Auto Balance for Vehicle Mods

This will force all modded vehicles to use the engine balancing for cost / maintenance rather than using fixed prices set by the author (if applicable), ensuring modded vehicles follow the same formula as vanilla vehicles, for balance reasons. This is particularly useful when using mods that alter vehicle stats. i.e With double capacity mods, vanilla vehicles would auto-scale costs, whereas modded vehicles with fixed prices would not, as illustrated in the screenshot above. It can be added / removed at any time
