It is interesting to see how logos change over time. I found a site that has a page titled “Car logos evolution”. The page has the changing logos of Mercedes, Renault, Volkswagen, Cadillac, Mitsubushi, Buick, BMW, Ford, Mazda, Fiat, Audi, Alfa Romeo and Peugeot.

The Cadillac logos on the page only covers the actual coat of arms to the first trademarked logo. Just this month Cadillac rolled out an updated logo design.
