To find it go to the Biltmore Hotel the end of Coral Gables. Turn right into the grass. You should see a secret pathway. Go through it. It should end around some building with stairs. Go up the stairs. Kill the Timmy Vermicelli (see Timmy Vermicelli.) inside there and activate the switch. Go back down the stairs and into your car/bike. Go through the pathway opposite the one you just went through. You should find yourself behind the Biltmore Hotel looking at a race track with a pit stop. Go to the pit stop and take the Made For Game Kart. You can race the racer there or leave. Once you found the Go Kart you could select it from the menu. This kart is always red and always has race designs on it.
