When you have completed the game and receive the backwards tracks,don't play them all!Just race the backwards Time Trial. On the second curve,a black sportscar will be parked.Don't care about him,yet. He will catch you in the first tunnel,just let him pass.He will be parked again when you arrive at the same area the second time,only now he won't catch you in the tunnel.In fact,don't let him pass you at all,cos he wont park again afterwards.If you beat both your opponent and the Diablo black sportscar,you will get the Diablo!I recommend to use the Lamborghini like green sportscar you earn when you shoot all the ships in the hypereasy ``Galactic``game at the start.
