In 2002 i bought a brand new TJ X model. I didn't know anything about jeeps. That TJ had a D30 front and a D35 rear. My first wheeling trip i snapped a rear axle shaft on the D35. So i started my research to see what i could do to beef things up. Long story short, i ended up putting a Ford 8.8 rear axle, a Super 30 kit in the front, ARB air lockers front/rear, re-geared to 4:88, installed a TeraLow 4:1 transfer case and ran Superior axle shafts front/rear.
All those mods were done over a period of about 3 years. I wheeled that jeep for almost 10 yrs before i sold it. When i was looking for a new JK i immediately knew i wanted to go straight to the Rubicon. I basically spent all my money on the first jeep to get it to Rubicon status or maybe even a little better.
With the Rubicon purchase i'm already where my old TJ was. Sure i'll end up doing mods to it but straight off the lot it already has more wheeling capability than my old TJ.
Plus i love the electronic locks in the Rubicon vs the ARB air lockers i had in my TJ.
Disclaimer: Yes i know dollar for dollar its less expensive to buy a base model jeep and then put your own axles, transfer case, gears, additional upgrades to it. But it depends on how hardcore you ultimately want your rig to be. For my wheeling/driving/daily driver style i knew that buying a Rubicon and then adding a few additional items was the perfect scenario.
And as others have said in this thread, its also important to factor in being able to 'finance' a jeep as capable as a Rubicon vs having to come out of your pocket with cash to buy the mods to build stock jeep.
Would i love to have a pair of Dynatrac ProRock 60's? You bet i would. And its not out of the realm of possibility down the road.

Just sayin. :bleh: :doh:
