Personally, I drive a 7 seater becase I have 4 kids. It has a 2.9 diesel engine because i tow a large twin axle caravan and its automatic because I am disabled. I accept that it may be seen to be a huge gas guzzler but it actually does about 35mpg but I dont fly my family abroad so perhaps my carbon footprint is not as big as some. My car is not a 4 wheel drive either. However, It seems i am going to get hammered for car tax. It is already £400 a year (£440 if you pay bi-annually) and in my own mitigation I have a big family and I need a big car. I know all of the arguements for and against.
Just one thought though, are Ministerial 4 litre Jaguars not gas guzzlers? They return about 8 - 10 miles to the gallon on a standard model and Lord knows what on one bullet proofed and padded with cast Iron?
