[5fix]

I took delivery of my champagne quartz m550i over tartufo/piano black last week. I had one day with sunshine and took a few photos.

The exterior color changes from brown/gray, to a silver/blue, to gold depending on lighting. I am very pleased with it after three five series in black, gray, and carbon black with black interiors.

The tartufo brown in the photos of the exterior is pretty close to actual, I took a few of the interior in the sun and they came out much more orange than actual. (I included one anyway.)
