We had our Citroen C4 picasso (5 seater) stolen in August and we're trying to replace it with something more fuel efficient, preferably an estate as we don't need a large MPV.

However we do need a car with a decent boot that will fit three car seats or two car seats and an adult in the back for long journeys. We have ~£4k to spend, would like something with less than 100k on the clock, would prefer petrol due to concerns over changes in legislation on diesel, and pretty cheap to run (we only do about 8k miles a year).
