James,
Bodies are generally out of aluminum and very soft to bend.
Check for accident history and gap lines.
Generally you follow the protocol when buying any used car.
They are generally robust and straightforward.
Some things are very complex on these.
I worked in the junkyard in my younger days and had a customer who wanted both front fenders.
About 50 screws and bolts holding each on. Some large and obvious ones, and many hidden small ones, bolts and screws, that is.
Check with the local Porsche club for hints and tips, and maybe a member has one for sale.
