Theft prevention.

Insure it for full value, then, if it gets stolen you simply build another one. I parked my gold 69 Swinger 340 all over the place. Just locked the doors and took all my stuff with me. It was insured for $30,000 which was more than I sold it for. Same with my Corvettes. I insured the last one (1972 SB 4-speed coupe) for $28,000. I sold it for $20,000 so if it got stolen....so be it.
Grundy has the best policy as far as actually being able to USE the car for what it is; a car.
