If he ordered quarters then you know it needs metal work. If it's only on the shell, and the rockers and pinch welds are in perfect shape and the trunk is clean and solid, I would not hold that against it too much.

Calculate the new cost of the aftermarket parts and if in great shape, divide by two as some will be unusable or distressed after years of storage, especially the top and decals. Measure the decklid, as some of the repros run a bit long on the driver's side and stick out beyond the tail panel if the gap at the front is correct.

Power seats are a very rare option. Cool find!
