i hope the zetec tdci lives up to your expectations dave,your a bit like me on your second st,mine is a 07 red although the performance on this is better if sometimes erratic,but i like the car.As a part ex you may get around £9000 to £9500 at a push,i got £9550 for my 9 month old 56 reg st against my red 07 st,good luck,by the way you say your getting too old what about me at 43 but when i get behind the wheel all of a sudden i feel like a 18 year old.
