Well let me start by saying this. I love all Camaro's and it is by far my favorite car, but..... I think if you asked this question 20 years ago I think you would have had a different answer. I think back then either the 55 or 57 would have won out. So I feel it is a timing thing. At this time it's easy to pick the Camaro because it is the car that so many recognize now/ have feelings for now, while those who were really into the 55 & 57 have moved on in age and many have different interest now. What Chevy is best well I will say there are a lot of great Chevys; 67-72 trucks (offered the first sport truck package), 62, 67 Vett, 70 Chevelle SS, just to name a few.
