yes you do, Vauxhall have Black Sapphire, Ford have Panther Black, Honda have Night Hawk Black, Land Rover have Java Black, not necessary black metallics as some of them have pearl bases in them, these are just a few of current black metallics / pearls available.
as king rat said, there are loads and loads of met black colors, look closely when you walk past a car that looks black, especially a newish ford and you'll see the sparkle in the paint.
