Bonus Car and Track:
Start a race in Hong Kong, level 5. When you get to the bridge, slowly drive across then immediately turn to the right. Drive back under the bridge and get the gold medallion. You now have access to a new car and track.
Extra Easter Island 2:
Start the race with any team. After the lava, go to the right off the track (after the S turn) and on to the grass just before the red and white road block. Follow the grass to a small beach. At the end of the beach you will find a gold object. Run over it for a new track...
