As much as I hate to admit it, I think Evan may be right.
The majority of us that own these are older, and we are living a dream that we could not fullfill when we were younger.
It's true that some younger people own these cars, and still more will continue to want them in the future. However that group will dwindle as time goes on. And then there will probably come a time when our government officials will go all out to ban them from the road and they will only be in museums.
Only hope that I die before I see that happen.
