So if I put a Jeep decal on my Dodge, that makes it a Jeep? That would also make a Compass or a Patriot a Jeep as well, using that logic. You've never heard of the Jeep Corporation, AMC Jeep, or Chrysler Jeep? The Jeep brand didn't exist till about 1970ish, the trademark around 1950ish. Prior to that the name wasn't part of the brand/ownership. However the Jeep existed. It wasn't a company or brand, it was a particular vehicle who's brand was Willy's or Kaiser, who's model name was Jeep, and who's model number was CJ for the non-military use version.
The Jeep is a specific vehicle, not a company or brand, which today's generation likes to think. It didn't have another model name like wrangler, patriot, honcho, wagoneer, etc. because IT WAS the Jeep. The vehicle eventually spawned a company. A company didn't spawn the Jeep. A company did spawn the wrangler and it was because they ended production of THE JEEP. The first Wrangler wasn't built in 1941. However, the first Jeep was.
"The quarter-ton Jeep earned a worldwide reputation for ruggedness and versatility in wartime. That tradition has continued for more than four decades that the CJ has been sold to the public. Completion of the CJ production will signal an end of a very important era in Jeep history."
