I read an article where a guy posed the question, "Will collector cars continue to be a good investment?" Now he was talking about the high end, vintage cars that we see at Pebble Beach, but I thing his thought process applies to our hobby cars, too.

When I was in high school and college in the late ‘40s, early ‘50s, a car was the centerpiece of a young man’s life. Chevy, Ford and Plymouth – they were all good and created lifelong memories. Then, when you drove your car to Monterey and heard an Jaguar XK120 boom through the old Pebble Beach circuit, you knew where your life was headed.
Much later, MGBs, Mustangs, Camaros, 914s, GTVs and 240Zs were important to us. And now that we have some money, we’re only too happy to write a big check to buy a memory.
Today, kids don’t care about cars. The sound system is more important than the car it’s installed in. So they won’t have significant memories of cars as they get older. And they won’t have any urge to acquire the dream cars of a much older generation.
He also pointed out that the younger generation will have a hard time paying the tab for a collection of cars, including the "value", storage space, utilities, insurance, etc when that money could be invested in other places to create income.

We've already witnessed a transition, where restored Model A's were all the rage ten to twenty years ago, but as the generation of the teens to twenties aged the value of vintage Model A's dropped like a rock. Is the same about to happen to the hot rods we enjoy? And how long before it affects the muscle cars of the "boomer generation"? As an example, I was at a local cruise Saturday where some guy had a blinged out late model 'vette that was literally shaking at the curb with the thundering bass and twang of his "music". It was so loud that walking by you needed ear plugs, and it was getting faaaar to much attention from the under '30 crowd. I fear that the guy may be right....
