Time to solve this.
1- French, active from 1900s til late 30s, the builder was an engineer, an inventor and an innovator rather than a businessman, he choose funny names for his vehicles, that have 2,3 or 4 wheels. He claimed a famous company stole his patents for a very popular car...
4- I'm not asking you to jump around in your room or to buy a ticket for a faraway land...in the same place where I found the Kangoo you can find this one...this is far beyond the clue!
5- If I post the pic of the side of a car, smooth and long like a torpedo, with the hood that slides on rails, Cadillac powered, taken from a Popular Magazine....
6- This one can't be still around! I can name at least 3 of you that are familiar with this car or at least know the place where I took it...and it's not a big site at all! This car was the cover-car of a magazine...I'll leave my last clue, just in case...
19- If you google the name of this car, you'll find dozens of results about John Wayne...(big clue)
(there is another point too, if someone can read between the lines of my previous replies....)
