there is a purple one near me on an 07 plate , up at £7995, which feels about £1k off the mark, looking around. and another, but 2005 in manchester area at £7400, 30k on the clock, plus the tax drops to £290 on that one.
Which ones did you go and see? They seem to be incredibly rare; I've been reading these forums (I'm interested in these but I already have a £500 road fund licence car, so am veering towards a 450H), and there is a few miles from me, but it's missing service history and seems highly priced considering)
