16. Mercedes SLK-AMG
During the early 2000s, a renaissance of different sports cars was hitting the market. The Mercedes SLK-AMG was one of these interesting cars that made consumers pause. That was, in the first rendition, but toward the middle of the decade, the car became an unimaginative piece of metal. Although there was a glimpse of the Mercedes SLK-AMG with the powerful V12 in earlier forms, the car was quickly overshadowed by other models on the market.
For a short time, Mercedes lost its luster and appeal for consumers by creating a sports car that was far from viable. The SLK-AMG did manage to garner a good deal of attention with its celebrity clientele, but that was it.
