Whatever happened to Jeep’s famous CJ or Civilian Jeep series from 1948 until 1986? Well, you see, it became the Wrangler! Yes, that’s why the two have some serious commonalities in terms of not only styling, but sheer off-road ability. The Wrangler nameplate took over in 1986, with some comprehensive re-engineering, but the basic principles have remained true to this day. That’s why today’s 1997 Jeep Wrangler Sport is a formidable off-road buddy to have. It’s got 118,000 miles and hails from Wichita, Kansas. Plus, it’s part of the TJ or second generation, which came for the 1997 model year.
