Easy Money
In career mode, go to your garage and do something with one of your cars (for example, switch a part or get a different paint job). The game should autosave. Then, go back to your race menu. Go in a sprint and bet all your money on one car that looks the fastest. It it does not win at least three races out of four, turn off the Xbox and turn it back on. It will load your last autosave. Try the same sprint again until you win then find a different sprint and start the entire process again.
Flying car
Get a Viper GTS fully tuned and go to the oval track. Drive about 210 mph. When you are about to turn, turn the other way into the wall. Hit the nitrous and hold it while still turning into the wall. If done correctly, your car should go up and fly. You must be in the dirt part of the turn. Try using the nitrous two seconds before hitting the wall and hit the wall (wire fence) at about a 30 degree angle.
Free metallic paint
Go to the paint menu in career mode in the workshop. Highlight "Metallic" and press A. At the color selection screen, press Y. Go to the base color and chose one. The original base color will now be active as a metallic color.
