10: Infiniti Q45 Second Generation
The second generation of the Q45 was an improvement over the original model. Gone was the extreme styling reminiscent of the first-generation car. The designers at Infiniti went for a more subdued appearance, but the problem was that styling trends were changing. While the Q45 retained a seemingly boxy shape, most competitors, including Lexus, had moved on (via Journal of Classic Cars).
The V8 was still the main selling point of the Q45, as it offered a lot of power. But luxury car buyers want more out of a vehicle, and the Q45 really didn’t offer it. At the time, the Q45 was the most expensive Infiniti on the road, and that isn’t saying much. The second generation of the Q45 sedan fell short in too many aspects compared to what else was on the market.
