Sorry to be the bearer of bad news.
You're gonna want this guy's pockets, once you start modding your Jeep.
Browse the forums regularly, you'll see plenty of tips on cheap mods ( such as painting your headlight bezels).
Also watch craigslist. You can often find used parts there when someone upgrades their suspension, armor, appearance, etc.
I see Jeep rims and bumpers pretty regularly on my local forum. Even the occasional lift kit and tops.
