Hi Irishmykl, I had my stock smart alloys powdercaoted black as the silver was starting to scab up after 4 years on the front only, the back ones looked like new.
Get it done the black alloys make the car look meaner, and over here in Britain it is the "in thing" at the moment having black alloys.
Here is a piccy of the wheels, see what you think!!!
