Jeep Wrangler generations: YJ, TJ, JK and JL

Jeep Wrangler history

The Wrangler descends directly from the 1941 Willys MB through the CJ-5 and CJ-7. When it replaced the CJ-7 for 1987, the YJ added a lower center of gravity and more comfort while keeping the removable top, fold-down windshield and solid axles that define the line.

The 1997 TJ returned to round headlamps and moved to coil springs, and the 2003 Rubicon made locking axles a factory item. The 2007 JK was the first clean-sheet Wrangler and introduced the four-door Unlimited, which turned the Wrangler into a family vehicle; 2,165,678 JKs were built before the last one rolled off the Toledo line on April 28, 2018.

The JL launched for 2018 with a new eight-speed automatic and a 270 hp turbocharged four alongside the 3.6-liter V6. The plug-in hybrid 4xe and the V8 Rubicon 392 followed for 2021. Jeep sold its five millionth Wrangler in August 2023 and says more than 80 percent of them are still on the road.[1],[2],[4],[5]

What to check before you buy one

• Pick the generation first, then the configuration: two-door vs Unlimited, top type, axles and transfer case matter more to value than the badge.
• On every generation, inspect the frame and body for rust, and look for water leaks around tops and doors.
• Lift kits and larger tires are common; check steering components, control arms and driveline angles, and whether the axle gearing was changed to match.
• Confirm Rubicon equipment (locking axles, 4:1 transfer case, disconnecting front sway bar on JK and JL) rather than relying on decals — the build sheet verifies the factory equipment on record.
• On a 4xe, ask for charging and battery service history; on a Rubicon 392, confirm the HEMI V8 against the VIN.

Jeep Wrangler prices and values

Medians of asking prices, not transaction prices; every trim is blended, so performance variants usually sit well above these medians. "Below new median" compares each model year's median used listing with the median listing price of a new 2026 Wrangler 4-Door today. More in our Jeep Wrangler 4-Door depreciation study.

Mileage: across 58,265 used Jeep Wrangler listings in our November 2026 study (all model years), the median odometer reading was 62,722 miles and 0.8% showed 200,000 miles or more. See how long a Jeep Wrangler lasts.

How to verify a Jeep Wrangler's factory options

Two Wranglers of the same year can differ by thousands of dollars in factory equipment — Rubicon axles, tops, Sky One-Touch roof, cold-weather and technology groups, gear ratios. CarWhere checks a Wrangler's 17-character VIN for licensed factory build data and, when it exists, lists the equipment it was built with. It does not promise a complete option list for every VIN.
