It seems that it was not just the Toronado that came in several distinct shades of blue but the good old Buick Riviera too. So far, all those I have encountered have been the same sort of of 'normal' blue metallic. Simply blue, I don't know how else to describe it. Now, though, along comes this quite clearly green-blue. It is much more noticeable in reality - the photos, despite my best efforts - don't show the difference as clearly. (I had the same problem trying to capture the difference in two Toronados, strangely enough.)
This one has come all the way from America. I was looking for a model with cast wheels which I'd spotted on one for sale. Unfortunately, all that I could find here were a very expensive blue one at around £200 and a tatty one with broken bits in gold. That was cheap enough but was beyond simple repair and I reckoned that it would be fairly easy just to change the wheels if I took it apart and then I couldn't prove that it was the rarer, late version.
So there are a few with cast wheels around and I guess they're not that difficult to find but they are worth looking out for. I'll buy a decent gold one when I find it. Finding the new shade was a bonus. The picture in the advert did look as if it was greenish but I'd put that down to light or just rubbish image processing.
