So long story short I sold my land cruiser a few years ago and now I want to get another one. I moved from Alabama to Ohio and found this horiable cancer that scares the bajesus out of me called Rust. I found a 2006 on auto trader that didn't show the undercarriage and after a 3 hour drive to look at it the undercarriage is rusty. I left the dealer not feeling I could trust them. The cruiser drove fine with 140k. The cross member has already started separating and looking like a flaky biscuit. Am I overly worring about the rust or is it really not a big concern and can be addressed with POR and starting to oil spray it regularly?
