Just to add to this thread. While i had been stuggling with the rad replacement last week in amongst everything else, i had used my Dad's car for the week and did just short if 500 miles in it. Its an 06 reg Ford Fusion 1.4 petrol with now 26k miles. Dont suppose the Fusion is the most exciting or cutting edge, but have to say that apart from being "tighter" than mine (with nearly 130k miles), it was miles behind the Stilo in its driving dynamics in every way.
No offence to lovers of the Fusion, which is no doubt a fine enough car, but just sayin'...... (particularly reference what i seem to remember at the time was a bit of a pasting which the Stilo got from the motor testing fraternity on its driving abilities).
