Many buyers prefer 1997–2001 for the updated interior and refinements, with condition and rust status being more important than the exact year when comparing well-maintained examples.

What should I check before buying a 1999 Jeep Cherokee?

Check for overheating, coolant leaks, oil leaks, front-end play or wobble, rust in the floor/rockers/unibody rails, smooth 4WD engagement, and a consistent maintenance history with cooling and fluid services.
