Living in NEw England the Rot is always prevelant but if you look you find the cars people who understand and put them away until after the salt is gone are. I have owned several and never dealt with bad rot. The strut towers at the edge in the engine bay are bad for rot and so is the floors. if you look you will find decent ones but also look at the drivers front tire alignment to the fender oppsed to the passenger side. I have seen a lot of launch bent cars where the drivers front is sticking out all cambered and no matter how much adjustment you have the tire is still tilting out at the top and usually the fender is out from the door as well. if you see this on a car keep looking its a bad bend.
