Need some help

Hi guys well if i ask you this i buy a Ford Mustang GT 500 i want it painted Black with Red Stripes and at the sides, it should say Shelby GT 500 but how do i do that and also what stripes do i need for it to look authentic?
i try the manufacturer colors but the black option is not with red stripes even thought it shows black and red how come?
so i need some tips for how to make some cars look badass :slight_smile:
