Luckily, my car is rust free! I hear the fenders, especially around the head lights are weak. As with any car, look around the battery. My windshiled wipers are all losey goosey, don't know if this is common or not, but mine have it! Some of these old cars have trouble around the hood hinges, I'm not sure if it applies to this model.
I am confused by you other post about a leaky gas tank. Have you bought this car? Post pix if possible and welcome to the club!
