Autostyling

Hi Everyone,

I am new in this platform.

Recently bought 2nd hand 2011 32Od E90.

I want to customize it, i.e. make the Rims black and also put in a spoiler.
Please advise of places I can go to to do this, at least must be reasonable in prices.

I am based in the Johannesburg/Midrand/Pretoria areas.

Regards
