1984 911 Carrera cabriolet wide body. True or fake?

[ClaudioB]

I am being offered to buy a 1984 911 Carreras cabriolet wide body, not turbo. Vin number WP0ZZZ91ZES150228. How can I figure out if this is a factory original wide body or an after market upgrade. I called Porsche USA and they informed me this car was intended for the European market. Called Porsche Germany and they do not give information unless I am the owner and have proof of owner ship.

I don't suppose the owner has the original build sheet or a COA? That body does not look like a stock wide-body to me. You could look up in the fenders, the inside of the flairs, and see if you see welded seams. Stock wide-body would not have welded seams. Also, of course, it should all be steel.
