A lot of these cars on this list are scary. Part of the problem is, few people had any sense that any of these vehicles would ever be collectible. I used to have a neighbor who had a 1984 Ford Thunderbird, and while it's not as valuable as the '83, I frequently urged them to preserve it as a collector's item. This was the car that started the huge aerodynamics trend of the 1980's and 1990's in the US.

They didn't listen.
