I've looked into this one and my answers as promised.
One of my original questions was 'who made it' - meaning, of course, who made the car pictured, not who went on to produce or market the car.
Since on the TJB Design website it says "Kit car project for which TJB Design designed and manufactured the patterns, moulds and first prototype." and as the picture shows, I believe, the first prototype, it follows that the car in the puzzle (not subsequent cars) was made by TJB Design.
I'll concede the the car was eventually called Delkit Camino, but that was not what I was asking.
This is of course AutoPuzzles where we may ask specifics, not general questions.
Your analogy of the Reliant Robin is incorrect, as of course you wouldn't call the production Robin anything but a Reliant, but the same rule applies to this car. As I understand it this car is not a Delkit Camino but the TJB Design Camino prototype. I may be wrong of course but it's my puzzle and I deem the right answer to have been given (by you of course!)
