definitley look for an early 99 cherokee, the difference between the early and late 99s is the front brakes and hubs, the early ones have full cast rotors which are about 10-20 dollars cheaper to replace, and the later ones have a composite rotor. the hubs are also cheaperto replace on the early 99s. i have a 4.5 inch lift and 33s with the dana 35 rearend no new gearing. i wheel the living hell out of it, but then again when i got a year and 4 months ago it only had 43000 miles on it. i have no drivetrain vibes or anything. i did not even have to replace or extend the breaklines and they still had about 2 inches of slack when flexed out all the way. i average about 14-17.5mpg in the city. like that one guy said the 99s have the older head and the newer intake. dont go for 2001 because they have the coil ignition instead of the distributor which is more expensive to replace, and they only have like 3 more hp. also if you can try to find a 2 dr 99, pretty hard to find those, and if u get really lucky ull find a 2dr ax15, 4.0,np231 like aircruiser did. and if she likes purplish colors find her an even rarer 2dr with the pearl blue plum color like mine, i have seen only 3 in my life that are that color and they are both 2wd 4drs.
