I've almost always owned one Jeep or another and currently own 2. If you're tired of dumping huge amounts of money into building a capable off-roader, get yourself into a Rubicon. I'll be starting with a Rubicon as a base for building from here on out because you just can't build a more serious off-road vehicle for the money. Buy one and drive it from the dealership directly to the nearest (and most extreme) trail and have fun knowing you'll go anywhere! I love my '04 more than any Jeep I've built (including a '59, '76 and an '88). The seats need lower lumbar support but it's more comfortable by far than it's predecessors. Save your "build-up" cash for something else - buy a Rubicon instead.
Capability ... period.
Seats need to be a bit more refined. Seatbelt can get slammed when closing door.
