>>4626397Sport is base model. Sahara is similar to base model but with better trim and appearance, and better tires. Rubicon is the best with stiffer shocks, better front and rear axles (Dana 44), best tires (BF Goodrich Mud Terrain), 4.10 gears, 4:1 low range transfer case, not to mention all the goodies such as 7 speaker sound system with sub and 6 CD changer standard (it sounds pretty gud), and of course, dat RUBICON decal.
I don't know much about the Mojave since it's new, but it seems like another appearance package based on the Sport like the COD edition.
