Unlike a normal car purchase, odds are really good that the Jeep you are looking at got to see something other than dry and sunny pavement in its life. Off-road and snow usage doesn’t automatically mean that the Jeep is a lemon. Check skidplates for gouges and dents and check the frame around suspension, body, and steering mounts for cracks or repairs. While you are under there, keep an eye out for surface rust and scale. Some surface rust isn’t a deal breaker, but flaky, scaly rust can be. If you find repairs for either cracks or rust, ask what the problem was and more information on how the repair was performed.
