i have one too. good car for if you cant aford a turbo imo.
yes its 3 seconds faster 0-60 than the 2.0 iirc. about 8seconds ish i think it was.
125 bhp as you said.
mpg i get about 34 average if i drive more economical ive had it up to 39 but that was driving rediculusly economicaly. if i floor it gets down as youde expect.
not the fastest car but still a good car.
can easily keep up with my mates abarth stilo which is a 2.4 leter car and same with my mates fiesta st so not a bad car imo.
cant get much more out of the engine with out spending lots, remaps get about 10 bhp extra and any more than thats going to cost a hell of a lot.
but still pretty good cars imo. if you need anymore info pm me.
