I'm looking at spending about £8000 on a car to replace my now tired 200,000-mile Focus. Since I'm doing over 30,000 pa, it needs to be both economical and comfortable on a long drive (120 miles a day). Bit of a problem with a lot of the small cars. If I finance over three years, I'll end with a car with at least 90,000 on it. I’m thinking of a year old Peugeot 207 1.6-litre diesel with 15,000 miles from Motorpoint for £8000? Or the new Dacia Sandero? What about an older high mileage new-shape Prius?
