2001 Jeep Cherokee Sport 4WD 4dr SUV (4.0L 6cyl 5M)
This is the second Cherokee I've owned. The first was an '87 that lasted 250k and would've gone longer had I not gotten water in the engine. For this reason, I decided to get a new one in 2000 (2001 model) and have not regretted it. The inline, cast iron, 6 cylinder engine will last a lifetime!
Things to look for; The rear main oil seal will leak at some point (both of mine happened around 100k miles), it's a gas guzzler, the valve cover will leak at some point (easy/cheap DIY), though my 2001 has yet to do this (140k), and the front rotors warp easily. I replaced my rotors with cross-drilled rotors that last longer, stop faster and cost less than OEM.
very reliable vehicle!
the engine, the 5-spd manual tranny, 4wd system
Better front brakes- the OEM disc warp easily and can't handle the weight of the vehicle. I purchased after-market cross-drilled rotors and it solved the problem for less money.
