R35 GTR
This means I get the return journey free as I have gained around 160 miles per tank.
This isnt a fluke, I first got over 50 mpg when I got the car, because i didnt know you could go over 3000 rpm. And another trip of 150 miles behind lorries, gave exactly 51mpg on the computer.
Obviously the figures arent exact, but this shows the car can be economical and fast! Just not at the same time.
