Cars are valued by their class and by their rating; and players can level up their car's rating with upgrades. A car's rating is made up of the sum of all of its upgrades. Each car has a beginning rating of 100 and a maximum rating of 24,000.
Purchasing Upgrades
Players can purchase upgrades for their cars by visiting the Mechanic Shop section from the My Account menu. From there, players can select which of their cars they want to upgrade and then select which upgrade they want to add.
Upgrades must be purchased in order. For example, you will only be able to buy the Engine Level 4 upgrade after first purchasing the Engine Levels 1, 2, and 3 upgrades. Some upgrades will require a car to have gained a certain number of Experience Points (XP) before they can be purchased.
