Infiniti M/Q70

The Infiniti M began in 1990 as the M30, a rebadged Nissan Leopard coupe and convertible. After a decade-long hiatus, the name returned on the V8-powered M45 sedan in 2003. The model truly hit its stride with the third (Y50) and fourth (Y51) generations, which offered a compelling alternative to German sport sedans with powerful V6 and V8 engines, rear-wheel drive platforms, and distinctive Japanese luxury.

Collectors are drawn to the M lineup for its value and performance. The later V8 models, like the M56 and its successor, the Q70 5.6, are particularly desirable for their potent 420 horsepower VK56VD engine and high-quality interiors. These cars offer a unique combination of reliability, power, and comfort that was often overlooked when new, creating a sleeper classic.

The market for the Infiniti M/Q70 is at an accessible point. With an average sale price under $10,000, these sedans represent one of the best performance-per-dollar values available. Early M30s are rare but inexpensive, while the best late-model Q70 5.6 examples command prices just over $20,000, suggesting the model is at the bottom of its depreciation curve.

Recent sales show a wide spread, with prices ranging from as low as $99 to a high of $21,000.
