hi mate my bro's got the fiesta st150. Its got shit brakes as standard, never really seems to kick u back in the seat and costs a fortune to get more power out of it for 20or 30bhp tops.
Apart from that seats are comfy which is good as daily driver mpg isnt that great although im not 100% on that.
All in all its not a bad little car but dont expect to much bang for your buck or you'l be very disappointed
