I hear there is a manufacturing problem with the roof, wether this is just supply or a technical issue I'm not sure. i got the impression it may be the latter.
I ordered my car 4 weeks ago, was told it would arrive December and indeed it is already in the UK and on its way to the dealer. If I'd ordered it with the roof I was told they'd not be able to give me a delivery date.
Be patient, it is dark outside anyway!
