I'm thinking about buying an '02 Tahoe. It's white. From about the top of the wheel wells down, if you look close, there are very small orange spots along both sides. From 6 feet away you don't even notice them. They are not raised like rust through. As a matter of fact you can't even feel them by running your finger over them. I don't know if this helps, but they are more prevelant on the drivers side. Anybody know what could have caused this? It looks like the dealer tried to rub them out because they're thicker behind the back bumper where you couldn't get a buffing wheel. I don't want to buy it, and have the whole body rot out in a year or two. Thanks.
