I've got a jetta 3 with metallic green paint - someone reversed into my driver's side passenger door, and it needed replacing. I ended up paying extra and resprayed the car. It costs around R1000 per section (i.e.: one door, boot, bonnet, roof). I know the guy who owns the place so I think he charged me a bit less. I think it cost something like R8k for the whole car - possibly closer to R10k if I had taken it anywhere else. It would be less if its just white, but it might be a problem if you are changing the car's colour to white from another colour.
