Purchase of V50 D5

Hello together, I plan to buy a V50 for July, as the current leasing contract will be valid. I would like to have a diesel with automatic, since only the D5 remains. My friend says, it is already available and indicates as delivery time 12-14 weeks. Does anyone have similar (or different) statements?? Does anyone have any comparison options between the 2.0D and the 2.5D (running rest, flow, consumption etc.)? Question about NAVI: can you enter destinations via postal code? says yes, at a demonstration (at the V70, Navi is supposedly the same) it was not possible!
