I remember years ago, the BBC did a whole program about Cut and shut cars, they had permission from some owners of a couple of cars that at the end of the program they would crash test them to show just how dangerous a cut and shut would be. One of them I remember distinctly was a mk3/4 escort cabrio in white (probably an XR3) that a woman had bought and later found out was a cut a shut.
When they crashed it, it performed way better than a normal car would have done. They tried to make some excuses about it not crumpling how it was designed to but in essence being a cut and shut made it stronger, probably because of a degree of seam welding in place of spot welds.
Anyway. This looks like it was kept well in a barn for a long time so has been dry its clearly not drooping in the middle in the photos of it, it probably isn't any less safe than any standard Uno of that era, which is to say it probably isn't safe at all by modern standards.
Mind you the range extension whilst sat on a trailer may be a good selling point.
