Do you know the edition numbers of the ones for sale? If you ask over on p1woc.co.uk then we might know more about the cars your looking at.
I have had mine for over 18months now ad has been used as a daily driver. Sailed through the mot's no problem. Only problem i have had was the 5th gear nut coming loose. Oh and seeing lots of shiney parts for sale that seem to attract my wallet a lot!!
