This is more of a business question than a technical question, but we don't have a business subforum and it's a business decision that requires technical knowledge. Now that the F-150 is made from aluminum, it made me curious about future trends, especially regarding low and mid priced sports cars. My question is specific to that segment. What will sports cars be made out of 5-10 years from now? Will the next Miata be aluminum, steel, improved steel or carbon fiber?
