I am currently driving about 650-700 miles per week (rarely on motorways) in my Laguna 2.0 auto petrol, and really need to change to a more economical vehicle because of my mileage. The Renault does about 32mpg and I am looking to replace it with something that will return 50+ mpg to reduce my fuel costs significantly. I have a budget of around £7500 for the new car and would hope to get something no more than four years old. Being six feet five inches tall, I need a reasonable amount of legroom, so would not really be interested in a small car. Saloons, hatchbacks, estates and convertibles, whether automatic or manual, are all OK.

I am happy to purchase from a large auction house (BCA/ADT) as my last three cars have been sourced in that way. I do not mind if the mileage is highish (80,000) as I will be adding a fair bit to it anyway. What do you would think would suit my requirements?
