with E R, i'd go w/ the black interior w/ aluminum trim, if applicable. (silverish color offsets the black quite well imo)
as for if you went w/ the white, i'm not sure what interior to get. black would be weird, beige would get dirty really easy, (esp if you wear a p coat or something in the winter, but yer in cali, so that doesn't matter) terra looks like well, dirt
from the website, but it may look way better in person. good luck
