I can't help you there, as the colour is always down to personal choice but I'm sure that you will enjoy whichever colour you decide. I visited the showroom to view the Kodiaq and didn't like many of the colours. Saw a small paint sample in the showroom and wasn't keen on the petrol blue. They had a quartz grey (never really in to grey cars) vehicle as a demo vehicle which I thought was one of the best colours out of those available and looked good on the Kodiaq and in certain lights seemed to have a blue tint within it, so I decided to go with that. Have seen it on the forum and really like the colour, in the shots that have been uploaded. Have also seen the petrol blue on cars within the forum and have to say that it looks gorgeous, so much so that I may well have chosen it had I known. I am very happy with my choice though so not a problem for me. Some of the colours have already been discontinued and replaced by others if you are not aware (not these two though) so when you see the new range you may decide on something different altogether. As I said earlier, I believe that which ever colour you choose you will be delighted.
