Depends...anywhere from two weeks to a month+, it just depends how many features you want in the interior and exterior. Obviously the more you want, the longer the wait. But the less stuff you add, the less time you'll have to wait.
But hey, one word of advice, before you order, think of what you will add to your Jeep if you decide to use it as an offroader too and not just a daily driver. I only say that because when you order, who cares about wheels and tires because you'll upgrade that stuff. And yes, the Rubicon package is way awesome, but those are in high demand and may take longer to get ordered to you depending what else you want with it. But just letting you know, my X package with a little lift and tires outperforms my friend TJ Rubicon, no joke...my JK dominates the trails.
So if you want your Jeep ASAP, don't be too picky. But than again, as corny as this sounds, "patience is a virtue"
