Here are a list of vehicles from the 1980s that I believe are considered very rare and generally not seen any more.
Ford Ranger (First Generation: 1983-1989/1990)
Jeep Comanche (1986-1992)
Ford Bronco II (1984-1989/1990)
Ford Taurus (First Generation:1986-1991)
Ford LTD Crown Victoria (1979-1991)
Ford Mustang (Third Generation:1979-1993)
Ford Tempo
I think if people want a old vehicle they probably might have to get a vehicle from the mid to late 1990s because the 1980s/early 90s are vehicles that are generally not seen anymore because by the way of their bad condition through the years. A 1993 to 1997 Ford Ranger is a truck I'm looking for because it looks very nice and they are more seed Ted the first generation Ford Rangers (1983-1989/1990). Likewise I want to know if these vehicles that I listed above are very rare and they are generally not seen any more on the roads.
