I am about to get rid of a 10-plate Smart car and I am used to getting between 45 to 50mpg. I have a budget of around £3000 for a second hand car and am looking for similar MPG?

I'd like something with a relatively nice interior. Interior is more important to me than exterior - I like an arm rest.

I am in need of more space (for the family at weekends) than a Smart car can offer so I am now looking at a medium sized car. I do like big comfy cars but need the mpg.

It should be an automatic, preferably, but that's not a deal breaker.

I do around 500 miles a week, on a few country lanes but 99% on motorways - I'm not scared of a high mileage car as long as you think it can live on and survive that mileage for 51 weeks (I give myself a week of rest) a year for 2 to 3 years - so reliability is also important!

I have been looking at roughly 8 to 10 year old diesels between 1.5-litres to 2.2-litres from Megane to Focus to Civic - pretty much anything that falls into that category.
