alot of places charge silly money for doing mondeo clutches.
round here the labour is about £250-300, some places its more like £400-600!
Mr Clutch at Leeds will do them for £180 supply and fit but they are recon units, i know someone who got one there and had no probs. or they may let you provide your own.
or find a decent mechanic who does stuff on the side, but be sure he knows his stuff because if the subframe isnt aligned right it wont work properly.
