I saw several when I was looking that were coated with heavy rust on the underside. Figured they came from up north. There must be a lot being shipped in. Looked at a buy here pay here place at a truck for my son and noticed every thing they had were rusted up bad. This one is completely rust free. I was really surprised when I inspected the underside. A few days before I found this one I found a 05 unlimited with 120K for 10500 that looked great in the pics. Drove 60 miles to test drive it. Pulled on the lot and the Jeep looked brand new,got closer and noticed the wheel wells had a fresh coat of undercoating. First thing I did was hit the ground and crawled under. That things underside looked like it had been sitting in salt water for years,I am talking heavy crusty rust like on a metal pipe that had been under water for years. I got back in the truck and left without even talking to him.
