A reg (1983) 4 door saloon chevette project

Right my mate has a 4 door chevette project that hes thinking of selling. Been dry stored since 2000 but needs a fair bit if work. The engine and box have been removed, both wings removed as it needs welding to the wing rails and inner a panels (the reinforcement bit), the passenger reinforcement on the a panel has been cut out, needs welding to the boot floor both sides as there's some big holes there, the sills need attention aswell. Its also had a small crash some time in the past and its pushed/creased near to the shock mount but not the leg itself so its still straight. What would people say its worth?
