Quoted:
the Willys Overland company has been defunct since sometime around when I was born (1947) if not before. A true Willys Jeep can be had, mostly from collectors of militaria, and will either cost an arm and a leg if comopletely restored, or only your left nut if in "restorable" condition....your other nut and leg will be used up in buying all the correct parts to complete the restoration.....
As usual Jim, if you choose to accept this mission and are killed or captured the agency will disavow any knowledge of your existance.
Willis-Overland produced vehicles as an independent company until 1953 when it was bought by Kaiser.
The name was changed to Kaiser-Jeep in 1963, which was bought by AMC in 1970 where the name was changed to Jeep...you can see where this is heading...
AMC was bought by Renault in 1979, then by Chrysler in 1987.
Chrysler was bought by Daimler in 1998, then by Cerberus Capital in 2007, then by by FIAT in 2010.
So, Willis-Overland is still alive today as the Jeep division of FIAT-Chrysler.
There is a company that was licensed by Daimler to produce Willis-stamped body parts, and has the right to call themselves "The Willis-Overland Motor Company:
