Last year I finished a low milage 89 240. 53k original. I went with cosmetics first, low miles right!. New paint all around, freshened the trim, interior, etc. A few months later I needed a new head gasket and head. The old head was too pitted to repair. Not a big deal but it was the last thing I thought I would need. You never know. It did give me the opportunity to clean up the engine compartment and make that nice too.
