16: Buick Riviera
GM needed an identity in the 1990s and as such the company released quite a few halo cars. The Aurora is one such car that comes to mind. And then there was the Riviera. The Rivera was a supercharged coupe with a lot of potential, a large interior, and a beautiful exterior design. But perhaps the design is a bit too polarizing for most consumers to swallow.
The Riviera ended up selling poorly for GM and the car was discontinued not too long after its initial release. There was a lot to like about the Riviera, from the exterior styling to the amount of power that came out of the supercharged V6 engine from the factory. But that just wasn’t enough to bolster sales of the car and it was discontinued.
