"Here's millage you can be proud of in a car you can be proud of". Sure. On a Diesel Cadillac. 1980 was the year GM started it's final self-destruction. Cadillac, with its Diesels, its V-8-6-4 engines, the Cimarron, and excessive downsizing, among other things, was the standard-bearer of that terrible decade for the corporation. And all that makes this ad from 1981 an interesting one to have for me.
