My battered old fiesta is reaching the end of its life. Another expensive MOT and service today and apparently the clutch is not long for this world. I don't have much savings (currently about £1000) and I'm managing to put aside about £200 a month now. I don't know how long the clutch will hold out for but clearly I need to start looking for a suitable replacement. I obviously can't afford a new car. I need some advice (I don't have a man handy or anyone motorish in my friends or family to help me). I need a small car, with low running costs, low insurance bracket. My only requirements are a big enough boot / back seat for my dog. What cars fit this bill and how is best to buy them - car salesroom, newspaper, ebay?
