I've found a 1981 version of this car and I'm getting it at a reasonable price, say about 3k USD. The current owner has had it parked up for at least a decade, I spoke to him and basically thought it would be just a shell I'd end up buying but I was informed that the engine and transmission were indeed working just some minor repairs to do. Other than that it needs a windscreen and just minor cosmetic work. I didn't get to a full checkup yet but if its rust free and the body is good should I try to rebuild/fix the original engine or would it be a crime to change the entire workings of the car with a different engine, tranny etc as if it were just a shell? Long story short is it worth taking the risk on?
