Yes, they are mega expensive as i found to my cost when i snapped up my 3dr CW Manual Ed 30 in early Oct.
I'm expecting to lose a fair chunk with buying when prices seem artificially high. But i'm intending to keep for 3 years at least so the pain may not be too bad especially with being a limited edition.
However, since then not a single similar car has turned up! As said, there are a couple of 5dr CW ones at main dealers but it has to be 3dr for me.
