I'll be the first to admit that the post-1967 front-wheel-drive GM luxury coupes aren't on my short list of cars I'd have in my garage. But I do respect them. It takes a particular sort to fall in love with a big, floaty couch on wheels. The personal luxury coupe market segment enjoyed a couple of decades of popularity in America, largely supplanting the muscle car during the 1970s. The king among these was the Cadillac Eldorado, billed as the World's Finest Personal Car. And this one is amazing.
