To win the Calsonic Nissan Skyline Race Car.
First buy or win a Nissan ( I got a Pennzoil Nismo GTR because I had the money) and race in the Amateur or Professional (I can't remember!) 'Race Of Red Emblem' and come first.
You will get quite a bit of money and a shiny, new, blue Calsonic Nissan Skyline Race Car.
