Sounds like your current Jeep is stock. In that case selling and buying would be your best alternative. Maybe even buy one that already has some mods and save even more money.
I agree; mods lose value really fast, so you can get the same for cheap. I bought a friend of mine a '94 Sahara with ALL kinds of goodies (33" BFG MT's, Mean Grean Alternator, 4" RE lift, lift shackles - I personally dont like that, but they came with the rig, OX locker, bumpers, rockers, winch, snorkel, flex-a-lite fan, aluminum rad, optima battery, aux lights, Borla headers and exhaust, etc.) for about about $6K last year... If I where to put all that in my rig, I would spend at least $5 or $6K (I put some of those, as a matter of fact). And he's been wheeleing it for about 2 years now with no issues...
