I think doing all that to the car would lower its appeal. It would to me anyway. It is original, in every sense of the word. Even the filters are factory fittings, never been changed, It's the rarity and originality that attracted me to this car in the first place. I see this as a museum piece, more than a car i would want to get in and drive. I am not sure how the engine runs, i have not attempted to start it. All the fluids would need to be replaced, but I don't want to touch it until I definitely decide what is to be done.
