switching salvage title to clear title
i'm sure they are but non are 100%. all that stuff can be hidden. there was a story on the news a couple years ago about a clean carfax car that had been in a major crash and repaired. think the car was sectioned. never showed up on a carfax. all that stuff can be hidden and not reported properly.
