luxurymods.com has the gold trim but, as far as I know, not for the 400h. I have corresponded with them about accessories and was told they could check on what I wanted, e.g. black pearl emblems. Steve at L-tuned would, of course, be a possible source as well. The prices ain't cheap. If I recall correctly, luxurymods gets $300 for the gold trim. But, it may be too soon for 400h-specific parts.
Your vehicle is silver???
