So far the thing seemingly getting the most varied comments on is the colour.
Some seem to be quite disappointed it's not red (but LEGO made the van red) or yellow.
Others love the colour.
I think LEGO probably picked the best colour possible. A quick Google search seemed to confirm my suspicion that one of the popular colours was a blue like this. I even found an old photo in the colour with a surf board on top.
It's even a great parts pack (if you can bring yourself to dismantle it), with 320 pieces in that (medium azure?) blue, including 26 that haven't come in that colour before!
