6. Jeep Cherokee
The Jeep Cherokee (XJ) was introduced in 1984 (after its predecessor, the 10-year-old SJ, was discontinued). Both two- and four-door versions of the XJ Cherokee were offered throughout its production lifetime, which ended in 2001. Interesting factoid: The Jeep XJ has remained a popular choice for off-roading enthusiasts. As a result, there is a thriving market of products and upgrades aimed at that audience.
