Hello Karan
Mk2 had chrome rostyles with black painted inners and grey painted rims
Mk1 had chrome rostyles with black painted inners and chrome rims
There could have been some early mk2s with chrome rostyles but most if not all had painted grey rims from what ive seen and read about.
The centres will be chromed all over then painted black.........you have to chrome whole rim as chroming is a dipping/plating process this would have then been masked and sprayed black..........you cant paint it black mask then chrome the wheel the process would destroy the paint.
They can look very nice with the grey painted outer rims and they do a sort of chrome paint that seems to be improving all the time
If you look around you may be able to find chrome trims that cover the rims which look good we used to put them on ford rostyles a very long time ago
