Carbon black or Space Grey 3.0sd M package?

[Beefy]

Which do i go for Carbon black or Space Grey 3.0sd M package? I must decide today. Must finalise the order tomorrow, what do you guys think, please give advise. I currently have the space gray 3.0 which is being replaced in Feb, like the colour but have had ongoing problem with the vehicle. I have changed with the sales lady 3 time already. Every alterate day i have a different decision about the colour. I have seen the M package in black it is awsome, not sure if it will be as good in the space grey. I was not sure if it was the carbon or saphire black. I did notice a few swirl marks already on the black. I know black is hard to keep clean but the grey also shows dirt unlike the Titanium.

PLEASE HELP ME MAKE UP MY MIND. i am confused.
