But at least now I can happily confirm that you can get 408 miles out of a tank of petrol in a Ford Ka. Admittedly, you will be stranded in the wind and rain if you attempt to discover this for yourself.
Haha i had this happen in my Xsara Vts. If memory serves me correctly it took 380 miles for me to discover this. Lucky it was a nice day, so i had a nice sunny walk to the petrol station on the A428
