Did you know that you can upgrade your car to make it better? It seems like you already know that. But, aside from looking at videos of popular YouTubers upgrading new cars like crazy, you can upgrade them to make your car better. The upgrades consist of the following:
The increments will vary for the vehicles rank and data at that specific upgrade rank. For each upgrade, it will get more expensive. For higher up cars, it will get even MORE expensive. You may see people dumping their S-Class Free Upgrades into their cars, but they are pretty hard to come by.
Every vehicle has FIVE (5) separate ranks before it is MAXed out in that category. It goes as follows: 1, 2, 3, 4, MAX. For bikes, however, they have 10 ranks before it becomes MAX. The bikes are cheaper to upgrade every rank level it goes up compared to the cars, because it has more ranks, so it can spread out the prices. If you upgrade all stats to MAX, you'll see a pop-up on the lower middle part of the screen stating if you have filled a MAX car in a MAX collection. If you fill the whole MAX collection, you'll get double the rewards from the normal collection. See more about collections by clicking here.
