Bear: if it helps, when I was looking at an A3 instead of the Golf, I was 100% sure it was going to be Scuba blue, as I see photos in the sun and it looked stunning.
However, when I eventually saw one at the dealers under a typical grey leaden UK sky, it looked just like a plain old dark blue, certainly nothing like the beautiful shimmering blue in the photos I'd seen. As the weather in the UK's normally crap, I just wonder if you would get the full advantage of it very often ?
