My dad had one about that age. The motor threw a rod with about the same mileage on it. Constant sitting isn't good for any engine.
It was tremendously underpowered also, a real pain to drive. You could only get it over 60 when going downhill and the throttle was pretty much on the floor whenever you drove it. A hill would drag it down to 40 pretty quickly.
I'm a huge toyota fan but I didn't like that thing at all.
