Paint dilema (HELP)

[chris-vw]

Right polly is going in for paint very soon i have an idea how i want it and both myself and my bodyshop guy are happy with wats got to be done

The only problem we are having is do i keep the bottom of the car the black plastic look or do i paint it and if i do paint it does it go black to match my other black bits or red and have it all colour coded at the bottom

What do you think guys
