Rotors and transaxles definitely normal. Remember these cars spend their first week on a boat in the Pacific.It's not like rust on the body panels where the metal's so thin it goes straight through, the transaxles are sold.
I'm not sure on where the other pictures are. One looks like a clip over the shifter cable.
