Nope, at least thats waht salesman said from dealership i work at. I dont see how they can be legaly forced to disclose this type of info, mainly because a lot of times they may not know for sure themselfs. But most of the time they do know, people at my place have a gadget that measures paint thickness so that you can see if there is a significant difference. Which gives a hint where to look for signs of body work.Thats why taking a car to get inspected is a must no matter where you are buying it.
