To me, there's a big difference between something done by a builder or carrozeria in period, and something cobbled up now. Not to say I'd want that car; on the contrary. But it's an original period, if weird and useless, creation, and I see something to that.
This is a genuine factory car, made by the factory for showing visiting dignitaries around the factory area. Thers quite a lot in info on this car. I believe they made 2. What you would do with it is an altogether different matter. For use on your landed estate probably? Or on your own golf course?
