It is a Mazda factory colour called Champagne Silver that was available for a short time on the SP20 (our name for a P5).
The good thing is there aren't a lot around in that colour. Most SP20s here seem to be yellow, black, regular silver and dark blue.
And yeah, it is a custom interior....very happy with how it came together
Rims are also custom bronze centres with some pearl in it, so they look a bit different in different light. ie more "gold" in bright sunlight, deeper bronze in shade etc.
Thanks for the positive comments guys. it's a "labour of love", you know the deal.......
