6: 1990 Dodge Monaco
There was a time when Dodge sold a lot of obscure-looking cars. The Monaco was one of these cars. This sedan was released from 90-92 as a stop-gap until the Intrepid hit dealership lots. The problem is Monaco didn’t fare well in terms of sales, and there were many more appealing cars on the road (via Edmunds).
It did have a unique look and spacious interior, but that was about it. Everywhere else, the car suffered from a lack of quality. To this day, Monaco is seldom seen on roads anymore. The build quality wasn’t good enough, and the design was ridiculous when you compare it to other models.
