As previously stated, the corrosion of the frame was total. After having GM cars for years I was use to their over engineering and experimenting on their products which they deny any responsibility. If they were not going to use good paint or undercoating on their products, they should say so when you buy it. I bought this car new. I have never had to wash the undercarriage of my car to prevent it from deteriorating nor has any car dealer told me so.
