Alright lads,
Being looking at getting a new car.
I want a mk6 fiesta but not sure either the ST or the Zetec S.
I do 50 miles a day for work (M3 and M25) about 350 miles a week just for work.

I've just given up autograss racing so want something which is good to drive aswell. My car at the moment is doing 37 mpg.

Is a ST too much of a fuel guzzler??
