Saveable..? 100%...the worst rot is an edge on the rear frame, really minimal...the rest is truly just a good wire-brush or at worst get it shot blasted.....then hammerite, job done.......spary wax-oyl in the tricky areas as the body-off option would be a mission in my mind.....all the wheels roll easily, the rubber hoses would need replacing as some have cracks and are weeping....a couple of areas on the glass fibre floors have started to perish but should be easily repaired .... the interior is very 80`s kit car, the seats are quite nice Recaro types...Re-strip the carpets and re-make them.. lots of potential.....The guy did say there was a number plate to go with the car too........likely a Q though.....he didn`t say.....
