The Jeep Wrangler Unlimited was introduced in 2006 as the third generation of the Jeep Wrangler family. Available as either a 2 door or a 4 door model, the Jeep Wrangler Unlimited has it all. Known as the Jeep JK, it was the replacement to the popular TJ model. The Unlimited is often equipped with a 4x4 variation although was offered with a 2x4 during its early days. Also worth mentioning, the Jeep Wrangler Unlimited offers drivers a standard transmission. Almost 3/4 of the Wranglers sold by mid 2017 were the 4-door model.
