Mine minus doors, interior wiring loom and fuel tank weighed 728kgs I think we weighed the doors with glass, window motors, etc at ~25kgs each, wiring loom will be a couple of kilos, maybe less there's not a lot of it left. I think 750 is achievable, wouldn't want to be used much on the road at that weight though. I've not weighed mine since I replaced the glass with plastics, there is also scope to replace panels with fiberglass ones, such as the front wings, bonnet and rear hatch. They are a light car, wouldn't want to have a big crash in one that's for sure.
