I am glad you continually caveat-ed this with "These are estimations" Because that is all that is going to come out of the other camp. I found the whole thing awesome, but as someone said, and I am summarizing here, "Ford doesn't care about ring times" and guess what neither do I. I don't mean that in an mean spirited way I just mean that the car is AWESOME either way. GM has very clever marketing folks and that is great, and I'd even venture to say they have a very nice product (EXCEPT STYLING!) but I made my choice for a reason. I love that this shows that the cars are competitive and maybe the GT500 wins. But I am just proud to own a piece of American Muscle history!
