not a lot i bet,best car ive seen for sale lately was a mint preface lift turbo at 6k....very rare these days to find one,i prefer the harder more aggressive look of the preface lift turbo over the later rounded facelift version but thats just my preference.finding a manual NA will be quite hard but possible ,but where do you find the stuff for a turbo conversion these days with no cars about?,you could source parts from the states for the conversion but if it was me i would wait to find the best car you can here,i can tell you though for nothing,preface lift turbo brakediscs are virtually impossible to find,new radiators are unavailable in the uk ...many parts are unobtainable although service items are easy to find,bodyshells rot anywhere and they do....especially prefacelift.,windscreens also seem to crack....if you find one and intend to keep it like me you will have to be a spares hoarder cos theres just none about these days
