- Karol Garage partner mission
Get the 'Idol' rank (33,500 Reputation) to unlock the Karol Garage partner mission.

- Teleport
In both offline and online game modes, you can teleport around the map by entering the race editor, switching out of 'drive and drop' mode, moving the pointer to where you want to go, then going back to 'drive and drop' mode, and exiting the creator. You will be where you ended the race editor.

- Free parts
Use the following trick to get free parts without completing the game. Go to 'Garage', and select 'Customize Your Car'. Go to 'Performance Parts', and press X to auto upgrade. This will check off all parts you can put on. Do not press A. After you press X, press Xbox 360 Guide. Go to your friends list, and join someone's session. Notice: You can also go to the recent players list for a better chance of finding someone playing online. When asked if you want to begin a multiplayer match, select 'OK'. When you get on the street, you will have the parts installed with no money deducted from your bank. This also works on any interior or exterior part, but the process is slightly longer to make the car you want. For example, highlight 'Front Bumper', then push X. Go to the bumper you want, and press Xbox 360 Guide. Join someone's game, and when you roll out of the garage, you will have that bumper. Quit the multiplayer game, return to the garage, and get any other part desired by doing the same thing.
