Collect the five hidden Derelict car parts for a Derelict car to unlock it. Each Derelict car requires you to have defeated a different league boss. After defeating a league boss, you will get clues for the five Derelict car part locations of a certain car. In the map menu, select the "Derelict" tab to view the clues. It shows a drawing with outlines of the streets where the Derelict parts are located. You normally would have to look at the in-game map and compare it with the drawing, but the videos below show all the Derelict part locations. The Derelict cars are special because they can be upgraded to the maximum level without the level caps normal cars have. After upgrading a Derelict car to Performance Level 300, it unlocks a Super Build for more extreme visual customization. After restoring a Derelict car, you can also choose which category you want it to be (Race, Drag, Drift, Runner, or Offroad). It is recommended you choose a different category for each unique car. None of the Derelict car parts are missable, but they will not spawn until you have defeated the corresponding league boss.
