    Older cars for sure did rust faster because the manufacturers didn’t adopt galvanizing until the late 80’s. Then in the 90’s various other spray coatings and sealers became common. Aluminum is also now prevalent to save weight.

    Old cars in the south and southwest didn’t have road salt accelerating the oxidation. But if they were brought up north they caught up quickly. Cars in the north prior to galvanizing would be rotted out in 100k miles easily.

      Neat, i’m glad we agree. Early 90’s is still very early in perspective to this audience. I’m driving a '92 and that’s 32 years old now. The cars from that decade last much longer than the 100k quoted above. Also, this is beyond 2.5X the average quoted in the OP article. Clearly, these are “old” cars. In sum, the 100k-till-rust-apart claim isn’t anchored in reality.
