What did the owner do, drive it through the ocean?? You have some surface rust cleaning to do.
You're OBVIOUSLY VERY uninformed, ALL Regals were delivered from the Factory with UnPainted And UnTreated BARE METAL Axles Housings and Driveshafts, Unless it was NEVER Exposed to AIR (H2O) it will look like this!! Many folks PAINTED thiers Black.... The GNX in the GM Musuem, the one they bring to Bowling Green looks like this!!
Well, my dads 55k mile GN has no coating on the LCA's or swaybar and it doesnt have any of that. Or axles for that matter. Just speaking outloud.
