Yeah i'll second all that mate. I find on the motorway it drinks like a fish , whereas normal driving it can be quite frugal, i never usually thrash it though.performance wise it aint as bad as i used to make out. its a good motorway car i find. pulling away can be sluggish unless you thrash it.
for economy its all down to your driving style.
anything from 35mpg upto low 40's will be average (is for me anyway)
although go over 65mph and the mpg takes a dip so i stick to 60mph
