Not that it makes any difference, but my reference says:
"The 1906 Paragon was the continuation of J.P. La Vigne's 1905 La Petite automobile that was built by Detroit Automobile Manufacturing Company, Detroit MI. He abdruptly decided to stop building the La Petite in 1905. When he did, he had a lot of material left over so he decided to build another car that was slightly larger and call it Paragon. The wheel base of 68 inches was the only difference between the two cars."
I interpreted this to mean that if the car was a 1905 it was a La Petite, but if it was a 1906 it was a Paragon. The company was sold in late 1906, and the new owners produced the Marvel (a totally different car) for 1907 (one year only).
