Our system says you're looking at about £7300 p/x for the Fiesta, so - plus your £6000 - you're looking at £11,300. This is an old model X1 4x4 or previous model Sportage 4x4 or ix35 4x4 (not a Tucson). The newest for your money will be a Dacia Duster 1.5 DCI 4x4. Qashqai have not been particularly reliable but, of course, are made in the NE so are well catered for there. If this is a bit depressing, the other way to go is to fit a set of Michelin Cross Climates or Goodyear Vector 4 Seasons to the Fiesta that will then be as capable in the snow as a 4x4 that isn't on winter tyres.
