I don't think it needs a full restoration, but it appears it could benefit from some deep cleaning/detail work. I know survivor guys like vintage dirt and cobwebs so I'm sure touching it at all would make them cringe.

The benefit of not restoring it is it remains a car you can drive. If you pick up a stone chip or two in this one it doesn't matter as I'm sure it has plenty already. People tend to go off the deep end with restoring these rare cars, and then they never get driven other than in and out of the car hauler.
