Bali,
I have a 180G with black interior. My sunvisors are light grey, which was one of the original colors, and subtle. I got a black wheelskin for the steering wheel. My choice is always for less bright, simple and subtle.
With the usual proviso on this forum, "it's your car, so do what you want," since you ask, I'll throw in my 2 cents.
I'd recommend minimizing the number of colors on the car. You have silver grey, with red interior, now you want to add white.
I think that this will be overly bright for your car, and will be the first thing noticed about the car. And this doesn't even take into account the wear/dirt attraction. Again, just my opinion.
What color is the padding on the dash? Probably black?
If it were me, I'd go with black steering wheel with black pad in the center.
Good luck!
