I purchased the car in June 2010 with individual night blue exterior over individual rust brown interior and was initially very satisfied with the color choices. Over time, I have become dissatisfied with the night blue as it appears to be black most of the time. The car has to be very clean and in bright sunshine for the deep blue to be visible.
This is a link to my first post re the car in 2010.
As I wished to keep the car because of its excellent condition and the normally aspirated V8, I decided on a color change. Also, the F82 M4 did not interest me because of the turbocharged 6 and its styling.
When the new M5 was introduced with the marina bay blue color, I decided to have a restoration level paint job done in that color.
Attached are images displaying the original night blue, disassembly, primer stage, finished paint prior to polishing, and the final product.
Overall I am extremely pleased with the result.
