All weight is underside
Growing up, my best friend's dad had one of these in his workshop. If I'd had the money, I might have been able to talk him out of it.
I just told Mrs Xue that we now have to buy one, and I found one, that looks a lot like that for a paltry fee of $80,000....she laughed at me....
In my youth, back when I was a mechanic, talking with the owner of the car, I came darn close to buying one of these

However upon close inspection..... I found the bondo in the roof he used to try and hide the fact that he had once rolled it. It was the early 80s and even then a Porsche 356, for less that $500, was quite the draw, but the whole being rolled bit changed my mind
