I'm a community mental health nurse who does approximately 23,000 miles a year, mostly in journeys of 15 to 40 miles. A good chunk of this mileage is made up of my daily rural commute of 78 miles, but I also travel to see patients and to the inevitable meetings. Obviously miles per gallon is a major concern, but I'm also keen to be as green as I can. At present I have a Toyota Yaris 1.4 diesel. I find this good in terms of engine size and mpg. It's my second Yaris. I'm comfortable with it, but find it rather dull. I get a lease car through my work, and will be entitled to a new one in the near future, and am wondering whether there might be another car that might also suit me.
