I actually haven't see the petrol in real life. It's on my list of things to do before I die... Hehe. Anyway I reckon the navy/blueberry will become popular if it gets discontinued as well. I think it is a SS 2007 colour. From what I have seen in pics, I think I could grow to love the petrol as well, but as baglady said, it'll be harder to find them. Esp in new condition. It's possible, but you have to be patient.
