As one who never was into cars, I'd have to say without doubt, American Motors made the ugliest cars, Hornet, Gremlin, Pacer, Javelin, Ford comes in second with its cadre of 70's cars that are as old fogy as you can get. I mean when Ford re-introduced the Thunderbird in the 70's and 80's with the 20' long vinyl top ugly pile "O" crap, that was the last straw. I'd place Chrysler next with some ugly stuff like the Dart and of course their trucks, but quite frankly, GM has had a better run of it throughout time then the others. The Aztec is a bottom feeder without doubt.
