I live 1/2 mile from the ocean in Florida. Mine doesn't look anywhere near that bad. The exhaust pipe is rusty, everything else is clean.
I do have some rust showing up in along the welded seam above the rear hatch area. Open the rear liftgate and look along the top edge, in the corners, above the weatherstripping. I had some pretty good corrosion in that area on both sides of the car.
