The "Black Cars" are a group of four secret racing cars featured in Gran Turismo 4 during days 694-700 of the calendar cycle. They are all painted, instead of in team liveries, in matte-black. There also seem to be some other random black cars, such as a Honda S2000 Type V '01 and a Clio Renault Sport V6 24V '00. If the player decides to buy all four race cars, a total of 8,299,978 Credits is required.
