Matte Black
They're all unique (even the two Matte Black paints look different) but there are no others that can be obtained by buying the car that carries it. Be advised that you only get 30% of the car's purchase price back upon selling, regardless of any modification. For more you'll need add-on content such as that provided with the Anniversary Edition as mentioned before.
