15: Infiniti M30
When the Japanese automakers entered the luxury car segment, every brand had a unique offering. Lexus had the SC400, Acura had the Legend, and For Infiniti, the offering was the M30 sport coupe. Available in a convertible or coupe, the M30 was a reasonable-looking machine. But shortcomings with the performance and build quality left drivers scratching their heads (via F31 Club).
Compared to other sports coupes in this segment, the M30 felt like it fell short. The model lasted for three years. During the years the M30 was on the market, there was also an economic recession. The car didn’t sell well enough to become a cornerstone for the Infiniti brand.
