I appreciate all the advice. As I say, I may fix it and sell it. But, just for grins, let's say I take the risk of keeping the car intact, sitting in our driveway, rodent proofing it, running the car for an hour each month, and periodically changing the oil. I understand that, if I do this, I will never be able to get the oil and ATF up to operating temperature. Can you guys elaborate a bit as to what harm will be done and over what lengh of time? And if I were, counter to the advice of some of you, to do this, how often should I change the oil? Every six months maybe? Thanks.
