If you're going to toss one, toss the 2011, has the 3.8L engine, not as desirable as the previous 4.0L nor the current 3.6L. The 1999 model Wrangler was one of the best made, due mainly to the stoutness of the engine. Newer engines up to 2006 are suspect; especially with 2005/2006 models. The cam sensor has a bushing that loses oil and will take out the oil pump below it, no good. 4wd dot com is the best out there for parts and accessories, Quadratec is noted for poseurs. Here's a shot of my first jeep going up Pritchert Canyon, Moab, 2001. Mustang v8, 36" swampers, shortened ford 9", HP Dana 44 front, detroits all around, etc.
