I’m looking to buy a used car, either a Ford Focus or Fiesta, which will cope with our growing family. I drive around 200 miles per week to work (60% motorway 40% usual roads), but I just don’t know what size engine to get as it’s not something I really understand.

I want a big enough boot for a pram and shopping. The car must also not be too cramped inside. What do you recommend I buy for £10,500?
