Mine has 250,000 miles and the driver rocker is kind of rusted, but the passenger side is still complete! It just depends on how you take care of the car. I always say that the engine will outlast the body, and so far, thats been completely true. And a heads up to owners of 97-00 grand prixs ( all models ) they have been know to have strut tower rust so if your planning on having any work done to it, check out the strut towers!
