12: 1963 Mercury Monterey
A lot of money was poured into the marketing of the Monterey when it was first released. The marketing showcased a car that was designed to make for family fun. The powerful engine and the rolling down rear window made the car unique. But that wasn’t enough to sell the Monterey and car fans were quickly turned off.
The high price tag and lack of practical features made the Monterey more of a novelty item than anything. The performance of the Monterey was still among the best of the time, but this isn’t what people look for in a car. There are other features that you need to sell a car and the Monterey was lacking in those areas.
