Hi.Another small problem I have with my 'b' is a small knock,or rattle which sounds like it is coming from the front right hand wheel region.It is more noticable on slow bumpy roads,but doesn't seem to affect the performance of the cars handling ,steering of general geometry.It has done 40k miles with service history,and seems to have got worse quite quickly,but no obvious loose bits can be found.I know the Mareas have weak wishbone bushes.Is there any similar weak point on Barchettas.Thanks all for your advice.Paul
