The worst thing you can do to a car is let it sit. As Craig said...You ain't seen nothing yet like master cylinder, wheel cylinders, power steering pump, A/C compressor, axle bearings, gas tank, fuel pump, carburetor, piston rings , valve seals, grease seals, transmission, water pump...the list goes on and on.
I had to move the car yesterday to allow a bucket truck in to cut a tree. the car rolls good while in neutral and none of the breaks are locked up. I figured that was a good sign. Just got finished pouring a quart of transmission fluid in the spark plug holes. It appears two of the pistons are up much higher than the other 4
