Come Heck or Highwater, there will always be a muscle car in my garage. For me driving is not just transportation although I have a truck for my everyday driver.
For me and a lot of other Americans, we have a love affair with our cars that will never end, never. Our cars in many ways are "Recreational" vehicles from which we derive much pleasure caring for them and cruising the roads.
Some people have passion for Boats, Bikes, Antique Aircraft (I fit this category as well) but the one thing we all share in common is passion.
No one will ever be able to legislate away our passion and even if they quit making muscle cars we will continue to care for them and become Stewards of a Legacy.
Heck look how long the Cubans have been driving their 50's model cars, if they can make them last 50 years so can we.

Hey my 1951 Cessna 140 is still flying at age 58.
If you have no passion in your life you may as well hang it up.
