Just on design (not quality or performance or anything else), as far as pony cars, I like the Challenger best, then the Mustang and finally the Camaro least.
Another design I liked, that wasn't very popular (and was severely underpowered), was the Chevy SSR quasi pickup. Not many other people did (apparently), but I liked the looks of it. :dunno: Course, my auto tastes are a bit odd, since I also liked the Dodge Magnum station wagon/"The Hearse" and the Plymouth Prowler. And it goes without saying that I liked the Cobra inspired Viper (mainly the 2nd generation - couldn't stand the last ones: Corvette wannabes). Yeah, I didn't care for the Thunderbird either. Pretty sad effort, IMO.
