I meant to write more, but I found this draft and decided it was worth posting as is. As you can see, a lot of them are favorites from movies, which is the primary way I end up seeing neat car designs, and and others are just favorites from my random browsing of car designs throughout history. I think it's interesting how car designs come to have a certain "personality," and say something about their drivers - which is on reason they're great for the movies, not only to play out the gearhead fantasy, but to build a character: you get a surprising amount of impression about a character, baddie or good guy, from their "signature" car alone.
