I'm expecting that there will be a bunch of less than 10 year old Camaros, Mustangs, Challengers, and Chargers there that not many people really look at like many other events.
Unfortunately, those cars make really good cruisers. And it is much easier to buy a newer car that is also faster than most old cars and drive it than to try and modernized the old one. And if you want to keep the old one stock, it makes the newer cars even more enticing.
Not saying it is right, or that I would do that, but it's hard to argue with AC, OD, CC, quiet interiors, comfortable seats, 400+ HP and 25+ mph.
Your car is there, and I bet most of the old cars on the tour will also be modernized at least to a degree. I wonder how many you will see that are not modernized, and of those, how many will make the Long Haul.
