i do find the 1.8 Zetec very lacking when you need that extra bit of power for overtakes etc.
Sounds like the Roadster is going to be the one for you......unless you fancy going the tuning route.
Did a bit of window shopping in Southport on Tuesday evening....Life's window was full of life !
New M3W and a +4SS in the window. Both looked very tempting.
Not sure if they have any roadsters available though.
