Part out or sell as project?

The reason is he is an insurance repair shop first, restoration shop second. He is the best in the area and has a constant stream of work. Used to be winter was a down time in the shop and he filled in doing restoration. Now he has 3 month back log just on insurance jobs. And it pays his bills. Can't blame him in the slightest as repair is his main income. But that means the Dart is just sitting in its trailer. Obviously patience is not a strong suit of mine, but it has been 4 years since I purchased the car and frankly the enthusiasm for the project is quickly waning with no progress expected in the near future.
