Whilst i like the vectra, the dobby does not have that much space (headroom) with the hatch down, so was wondering about the signum

If some has got the time could you please tell me a few measurements?

Distance on Floor diagonally
From the back of the seat to the hatch window(closed)
From the floor to the top of the back seat (Straight down)
Width of the hatch area (Max and Min)

Thanks

Phil
