I remember the last time this happened. It caused the mass extinction of all the muscle cars. We suffered. America lost it's lead in the auto business. Several generations of otherwise normal men became whipped woosies (if you don't believe this just watch reruns of "That 70's Show"). But, evolution being the natural force of things that it is, over the next 30 years new breeds of cars emerged, bigger, better, faster, safer, cleaner, more fuel effecient, and yes, more expensive.
Now a new environment threatens the very existance of the new horsepower race. I fear another mass extinction is near. But fear not, for a new breed will again emerge, perhaps burning hydrogen, perhaps not, but our grandchildren will themselves become the new race of pistonheaders who will enjoy the next horsepower race. They just won't have cool wheels 'cuz cars probably won't have wheels by then!
The bones of dead classic Mustangs will continue to be excavated and restored to fill the gap until that day comes. Perhaps that faint glimmer of life will sustain the generations of yet unborn Americans who will not wish to become the woosies of the future. Their fate rests in our hands. We must preserve our Mustangs until a newer better day returns.
But, you know, I bet our Mustangs will still be cooler than theirs will be!
