Summary Verdict

Potential buyers should be aware of the possibility of cracked cylinder heads on the 4.0L, rust on the frame and body, and electrical gremlins due to aging wiring. Transmission issues are less common but can include shifter linkage problems on manual transmissions. Suspension components like bushings and shocks are also wear items that may require attention. Overall, with proper inspection and maintenance, the 2000 Wrangler can remain a reliable vehicle, but be prepared for potential repairs common to vehicles of this age.
