The Ultimate Guide to Jeep Wrangler VIN Numbers and Vehicle History Reports

There are very few iconic SUVs purpose-built for off-roading. Sure, there are various Land Rover models that, other than the Defender are mostly built for looks, and Jeep has recently found a worthy competitor in the new Ford Bronco. Toyota also has the reliability niche covered with the 4Runner and Land Cruiser. But the Jeep Wrangler stands apart as an affordable and beloved embodiment of ruggedness and adventure. Since its inception in 1986, the Wrangler has catered to off-roading enthusiasts, adventurers and those looking for a distinctive driving experience.

History of the Wrangler

Building on the success of the CJ (“civilian Jeep”), the Wrangler carried on the lineage of a rugged two-door off-road vehicle with just enough amenities. Over the decades, the Wrangler underwent several evolutions while retaining its iconic design, removable tops and doors and impressive off-road capabilities. 

Wrangler brings various four- and six-cylinder engines, available with manual or automatic transmissions, but the full-time old-school four-wheel drive is available in all years and trim levels. 

Modern Wranglers bring a comfortable ride, necessary safety equipment and desirable tech for a capable commuter. Make no mistake, though, as the modern Wrangler still has almost no equal off-road competitor. If charisma, history and rugged adventures are your thing, you should get behind the wheel of a Jeep Wrangler. 

Well known for its stout and reliable 4.0L inline-six engine, the Jeep Wranger, like any used vehicle,can suffer from ignored maintenance or hidden damage. To protect your investment, have a vehicle history report performed for an in-depth look at its history. 

Second-generation Jeep Wrangler (1997-2006)

Retro vehicles were just getting hot in the late 1990s, and the freshly restyled 1997 Jeep Wrangler might have kicked off the trend. Classic round headlights returned to the traditional upright and blocky design, making for a fun and charismatic exterior that harkened back to 1940s military Jeeps. 

Underneath, the Jeep Wrangler TJ swapped out leaf springs for smoother riding coil springs. A stiffer and quieter chassis makes this Wrangler a better road warrior than earlier Jeeps, and the addition of driver and passenger airbags improved a daily driver’s safety. Classic characteristics like removable top and doors survive, as did the 4.0L six with available manual transmission.

If off-road adventures are your thing, look for a Wrangler Rubicon for added 4x4 toughness. Rubicon features a lift and upgraded springs and shocks, which increases the ground clearance and approach/departure angles. Sahara is the top-tier trim, with a standard 4.0L, wider fender flares, bigger tires and an upgraded sound system. 

If you want a two-door Wrangler with additional interior room, look to the longer wheelbase Wrangler Unlimited, starting in 2004. No matter the year, the Wrangler TJ has the off-road capability you want, as long as you don’t mind giving up some modern comforts and tech.

Third-generation Jeep Wrangler (2007-2017)

The new Jeep Wrangler JK brought modern enhancements to a revised-but-classic look, and Unlimited returned as a four-door option. It would prove a strong seller, with the majority of Wranglers having four doors in just a few years. 

While at a glance the new Wrangler looks very similar to the previous model, it is actually five inches wider for increased interior room and stability during off-road shenanigans. 

In order to reduce weight, the front fenders changed from steel to plastic. This generation gained electronic stability control to improve on-road emergency handling, and heated seats to improve your mood during winter. 

Powertrains varied by the year, with a 3.8L V6 until 2011, and then a 3.6 that is still available today. If you are new to Jeeps, the 3.8L might be an engine to avoid, as it only had 202 horsepower. It has a reputation for cracking exhaust manifolds, and it’s relatively slow. 

The 2012 model with a 3.6L has 285 horsepower, with improved reliability, gas mileage and much easier highway acceleration. The Jeep Wrangler JK is a great option if you are looking for a four-door Jeep with off-road chops and on-road civility.

Fourth-generation Jeep Wrangler (2018-Present)

Since the Wrangler JK was old enough to be a tween, it was time for a reinvention. The Jeep Wrangler JL is the latest iteration, bringing traditional style with the forward-folding windshield and removable softtop and hardtop. Curb weight increased, as did front and rear overhangs, meaning the Wrangler JL isn’t quite the extreme off-road brawler anymore. 

The newest Wrangler brings refinement instead, with an 8.4-inch UConnect infotainment system, Apple CarPlay and Android Auto, Alpine audio system and a nifty TrailCam feature, while trims like the Islander offer a beach-themed interior design.   

There’s engines aplenty to consider when shopping for a Wrangler JL. A new turbocharged 2.0L four-cylinder delivers more torque than the V6, so it’s worth considering as a rock crawler. A fire-breathing 470 horsepower 6.4L V8 is available under the hood of the Rubicon, and it’s able to toss the Wrangler from a stop to 60mph in just 4.5 seconds. That’s about the same performance as a Nissan 370Z. 

The plug-in 4xe trim only offers 20-ish miles of range on just battery power, but the 49 MPGe in combined driving is enough to rival a Toyota Prius. The Wrangler JL is the peak of Jeep Wrangler refinement, power and tech, with a slight drop in off-road prowess compared to earlier versions. Consider a Jeep Wrangler JL if you demand the latest safety tech and a comfortable ride while heading to the campsite.
