At least to someone who doesn't see much F1 racing. See, if you take an average person off the street who knows a little about cars, and then show them a picture of a ferrari F1 car, they won't know much about it other than that it's just another F1 car. Or maybe they'll say it's a cart car, or something like that. It's kinda hard to tell, they all seem to look alike if you don't look closely.
But in general, you can tell a Diablo apart from an F50 or a Viper easily, and your average person who knows a little about cars will probably be able to tell you their names, or at least the company that made them.
