I have just these ads...
I can tell you that this car has got an aluminum body, a plexiglass dash and many options, including 4-6-8-cylinder engines.
If you had few $ to spend those days you could have a brochure and color prints.
The Trikes are a different story: they were sold in kit-form or turnkey.
In one ad, the company, the address and all the rest is the same of the puzzle car and the trikes are called in a certain way...in another ad, the way the trikes are described became the company name, still maintaining the same address, telephone number and so on...
Probably this may lead you to the (half) solution.
