I just bought an 06 coupe and its carfax says its a southern car, but I have found some rust on the pulleys, some bolts(bolts with corrosion), and the block has some spots of corrosion on it. Should I be worried about this or just go ahead and start replacing the bolts, pulleys, and having the other items cleaned? Its not terrible and I can get some pictures, just need some advice on what I should do.
