Am rebuilding one myself at the moment,unfortunatly they not realy worth alot at present,parts are not easy to source as they were only built for a couple of years, i think in time the values will go up , as for making into a cossie replica , well you would be doing it for yourself as again you can spend thousands but not worth much once its done. Good luck with the car i would keep it standard if i were you if its that clean.
