After seeing my first Space grey coupe yesterday (coutesy of member bmwmike), I now realize how few if any of the photos really capture the true colour and its richness.
Of all the photos of Space grey on this thread, perhaps the 1st, 3rd and 4th photos above come the closest to reality. But even these photos are a pale imitation of the real Space grey. The coupe looks very handsome and classy in this colour. The strong silver metallic flaking in the paint does not seem to come through in the photos. IMO, this is the best silver/grey colour that BMW has introduced since Sterling silver. Space grey has no odd undertones like Sparkling graphite (can appear eggplant in the sun). If you like a rich grey look, Space grey is a great choice. IMO, the coupe looks much better in this colour than TiAg.
