Does anyone know of a decent garage who would change the cambelt etc on my 2002 ST170 in the Caterham/Croydon area ?

I don't want to put it into Ford as they'll just rip me off for loads of cash, but I would like to use someone who comes recommended and knows the ST170.

Looking to change cambelt, tensioners etc. and probably the water pump and aux belt(s) at the same time - willing to supply parts myself if that helps.

Thanks

Pete
