If you can stretch your budget to the 99bhp Puretech 100 petrol you'll have the pick of the range. The Puretech 100 is a really strong engine that picks up well from low revs; it's absolutely ideal for propelling you along on A-roads and motorways without any fuss, and livelier than a Clio or Polo with equivalent power. It's pretty quiet and we also managed nearly 48mpg in our trials, which is impressive.
