This us jeep style as been converted and evolved over the decades to meet the modern day needs of civilization. From 1945-1986 the CJ jeeps began transitioning from post war to power house farm equipment. "By 1948, you could purchase a Jeep in Emerald Green, Potomac Gray, Picket Gray, Michigan Yellow, or Normandy Blue. Their patriotic names were meant to symbolize hope in a post-war America. The CJs were a popular vehicle, and eventually, there were seven iterations of it."

In 1986-1995 the cj jeep which is now known as wrangler YJ. "The first Jeep Wrangler YJ debuted in 1986 at the Chicago Auto show. Its rectangular headlights gave it a new face, and though it continued to have the same separate body and frame that made the CJs so popular, it borrowed its suspension and interior from the Cherokee. The YJ Wrangler was more comfortable than the CJ and handled better. It also had anti-roll bars to combat the fabricated claims of increased rollover."

In 1996-2006 " Wrangler offered major improvements periodically, but the TJ was the first true second-generation Wrangler, produced more than a decade after the first. The Jeep Wrangler TJ debuted in 1997. Jeep had learned from its wins and losses. They increased the stiffness of the frame and body but also switched to coil springs to improve the smoothness of the ride. They also returned the Jeep's original round headlights, to the joy of Jeep enthusiasts everywhere (they really do look more friendly than the angrier square ones)."

The roll bars, the removable doors, the fold-down windshield, and the soft top were all still available. Even as Jeep offered more options, it maintained the ones that had made it first popular."

With maintained off-road performance and an improved on-road presence, the JL offers features that distinguish it from the JK while still heralding back to that first military vehicle from WWII. Understanding that off-road customers care more than ever about staying connected, Jeep wisely added comfort features like Bluetooth compatibility, and though it still comes in a six-speed manual, the automatic has been upgraded to an eight-speed. Additionally, even more safety features were added, included parking sensors and blind-spot monitoring.
