I truly think that the phrase "no rust" on any unrestored car will never be true. I think if you see it, even as patina, or slight surface rust on body seams and other places where the paint has worn through to bare metal, just call it like it is.Unless they think buyers are clueless, which is more of an insult. Its all the nooks and crannies where the rust hides that has the potential to become actual cancer. That van could continue to live happily in CA with no issues but if it came up here where its raining half the year, it easily will turn into real rust. We are battling it currently with 2 vehicles in our stable.
