I hope Ron doesn't mind, but he started a very interesting thread over on the SAAC Forum about Rick Kopec's "What's Your Beef?" web article. Rick Kopec explains what bothers him. It's very interesting reading.
Discussions seem to be most centered on the following topics:
1. 1965 1/2 or the "Carryover" Shelby Mustangs, why they should or shouldn't be worth more than a 1966 Shelby Mustang, and to a lesser extent
2. Fakes, replicas, continuation, tributes, clones, interpretations, adaptations, etc.

Fun reading.
