I'm generally not a fan of red cars, but when I went to check out my FR-S at the dealer... man, this car looks amazing in red! Like everyone has said, it looks good in any color though. The red really stands out, which is a good thing if you like to be see... but a bad thing because it makes you more visible to police as well. haha
I'd say check some out to see how the colors look in person, it's definitely a different view than just looking online. Good luck!
