just a little about the process , since you are asking about it
i have done it the professional way.
first you paint using any normal car color
in my case it was mercedes 972 (maybach black) but in the re-paint i might move to Lamborghini 1019 (Nero Nemesis)
afterwards you apply SuperMatte laque and Hardner.
the result is different from normal paint since hand marks etc are easily seen on matte lacque but you really can't scratch it and it is resistant as normal paint.
the downsides is that you cannot polish or wax the car. polish will make it shiny.
the process is much harder then using normal lacque since on matte it is very easy to see the air pistol strokes so you really have to make long strokes to make it work , which they haven't done now.
as for the rims , i really dislike the cupra rims. i am thinking on BBS LM rims and painting the center in the same matte black as the car. i really like deep dish rims.
