The CJ was in production from 1944 until 1986. Twelve different model types were produced in that time, although if you separate them into their various trims and submodels there are literally hundreds of variations.
The first of these utility vehicles was the CJ-2, which was not sold to consumers. Only 11 are still around today.
The CJ-2A was the first model offered to the public. It was made using lots of military surplus parts. The target market was vets returning from war who needed that versatile utility vehicle with excellent suspension and handling compared to cars of its time. It turned out that this market was bigger than they ever expected. Over 200,000 of these first models were sold.
Marginal upgrades were made throughout the years, but the major change came with the CJ-5, the most popular of all time. Some of the body types and variations of this model include: Tuxedo Mark III, Camper, 462, Renegade I, Renegade II, Super Jeep, and Golden Eagle.
The CJ-8 introduced in 1981 included a new body type for the model line: the CJ-8 Scrambler pickup truck.
You can find Jeep CJ's in just about any listing of used cars. They are popular with young people, hunters, and farmers alike. The number of aftermarket add-ons is limitless. Try looking at what they've got listed on eBay for the CJ.
