Jeep has one of the most remarkable histories in automobile land. Designed originally by American Bantam for WWII, it was produced by several companies during the war, including Willys and Ford, as well as Bantam, who did not have the capability to produce as many Jeeps as the war effort needed. After the war, Willys had the Jeep and built it's entire company around them. In 1970, AMC purchased the company specifically to get Jeep, and then, in 1987, Chrysler bought AMC to get Jeep! In the late 90s or early 2000s, German company Daimler-Benz purchased Chrysler, with many people believeing that Jeep was the main reason for purchase. That firm has now been broken up, with Chrysler being it's own company, and now Italian firm Fiat having purchased most of it- I don't know if getting Jeep was the main reason, but it would not surprise me.
I have a personal connection to Jeep as well. Since 2003, our family daily driver has been a 1994 Grand Cherokee, and although there are no pictures of it, when my parents met, my dad was driving an early 60s wagon as his daily driver- I believe he told me it was a 1964 model. (I wish I could find the notes I took when my dad gave me his list of cars owned!)
