9: Infiniti Q45 Third Generation
The third and final generation of the Infiniti Q45 was also a bit of a letdown. The styling was commonplace for a sedan in this price range. A fully-loaded Infiniti Q45 could easily top $60,000.00 with all the options. A comparable Lexus LS400 offered more luxury and performance for around the same price tag. Another drawback with the Infiniti Q45 was the lack of advertising and visibility (via Car Gurus).
There were only about 1152 of these sold, and part of that was a lack of advertising by Nissan. The brand was more focused on the G35 sedan and coupe at the time. Had Infiniti invested a bit more in advertising for the Q45, the model might have improved against the competition. The final incarnation of the Q45 is by far one of the least recognizable Infiniti models on the road.
