9: Ford Ranchero
Ford tends to copy GM when it comes to a popular product and the Ranchero was their version of the El Camino. Unfortunately, if the El Camino was bad then the Ranchero was especially bad. The design of the car was a sole rip-off of the El Camino and this was not an original design in any way (via Car Survey).
The performance of the Ranchero was also questionable and doesn’t justify the money you’ll have to dump into it. Even with modern upgrades and modifications, the Ranchero isn’t worth it. Unless you’re a diehard Ford fan, there are much better cars from this era that will provide more excitement.
