Go to the garage on the map, look at the expensive mods that you can add to any 7 lowriders in the game (Blade, Broadway, Remington, Savanna, Slamvan, Tornado and Voodoo). Head over to the lowriding competition and place your bet. I suggest betting $1000 because for one the beat is slow and then your competition really sucks. He'll be 100 points down from you most of the time. Juss follow the rhythm and controls. When that's done, watch the cutscene.
