Howdie owlcore, it's a ltd edition. Only 200 made in 2008 for UK market (just under half were 50s). Vespa now make lots of ltds. This one was eagerly awaited because it was the new S, supposedly the last of the 50cc 2-strokes (new EU emission regs), and supposedly a unique colour. The colour 'Taormina' then made it into the range. And they still make a 2-stroke (albeit slightly strangled to meet the new regs). They had a premium price at launch but now, as the graphics are the only difference, they get the same price as any other S.
The graphics do make it stand out to the uninitiated. But a Vespa spotter will know it is a standard S.
It might be urban myth so don't take it as gospel but two dealers have told me that many didn't sell. The £ fell against the euro and the standard S became more expensive. Dealers apparently removed the graphics to sell as the standard S. So, if true, there are not 200 out there.
