these mpg figures..are they what the computer is saying or what you get by checking miles against filling up? I had a mini cooper S that used to say I was getting 36 mpg but I gradually realised I was actually getting 24 ish. Quite a difference. I average a real 35 ish in my 2005 roadster (that's if my mileometeris accurate???) which is pretty good and important for me as I'm a) not wealthy and
b) have to look my clients in the eye when I arrive in it and claim it's economical
