BlitzenWerk 2002 BMW 530i E39 5sp M Sport
These are the dealer photos from when I purchased the vehicle in late 2005. The automobile was "just" still under warranty and had about 24k miles on it. The color of the car in these pictures is pretty accurate for the car on overcast fall/winter days. But, that said, the car takes on a much deeper and immersive blue when properly waxed with lots of sunshine.
IMHO the car looks entirely different and unique when properly waxed... One thing, in particular, are the subtle styling lines around the nose that become more pronounced and defined as the finish becomes more liquid and mirror like... but then I'm a little biased.
