I'll be interested to see how accurate Car & Drivers prediction was. Really looking for some weight loss in the next one! Although the current car is a looker (especially the GT500) it is just too big in both size and weight. The '03 Cobra is probably my favorite "modern" Mustang for its tighter appearance. I'll also be interested in the direction styling goes after the retro fad.
As for myself, I'd stick with a '67-'68 Fastback.
