Super Turbo Guide Price?

I'm hoping to be in the market for a March Super Turbo early next year and was wondering if anyone had some kind of estimated guide price for one? I thought £3000 / 3500€ for a standard model would be an accurate estimate but some people seem to pick numbers out of a hat as a price tag :L Any estimates or purchase prices and dates would be helpful. £2100ish in 2011 is as far as I have got. Cheers!
