Dunno you can get a Mk3 2.5 Zetec S with nav if you look really hard for that sort of cash, think i'd prefer the newer car.
Edit: Tax issue clearly but its not much money imho.
Thats what i originally thought, 2.5 mk3 mondeo fits the bill at the original budget.

) We have to trek up to yorkshire to see the inlaws and for that reason we really had to get diesel. My wifes Leon TDI gets us there and back and shuttles around on the weekend in one tank.
